Introduction
Welcome to the VibraImage World! Thank you for your purchase of VibraImage
system. This Manual is written to help you enjoy vibraimaging and open new features in well-
known objects!
VibraImage technology measures micromovement (micro motion, vibration) of person by
standard digital, web or television cameras and image processing. Human head microvibration is
linked with the vestibular-emotional reflex (VER) of a person and reflects emotion status and
personality traits. VibraImage system detects human emotions by the control of three dimensional
(3D) head-neck movements and fluctuations, accumulated as frame difference in several video
frames.
Fig.1. Frequency vibraimage of the person Fig.2. External vibraimage around
the frequency vibraimage
VibraImage is a new image type and so primary, as original color image, thermo image or x-
ray image. Each image type gives new and unique information about the object. Every pixel of
vibraimage reflects vibration parameters - frequency or amplitude (fig. 1) of vibration. One frame
visualization of vibration frequency and amplitude named external vibraimage and looks like aura
(vibra-aura) of person (fig. 2). Typically, external vibraimage colors linked with vibration
frequency and external vibraimage dimension linked with vibration amplitude.

2. Before you begin
2.1 Operating limits
Power supplies requirements for hardware
1. Power supply must be 220 V in 50 Hz via an uninterruptible power supply (UPS) with
feedback. UPS capacity should be sufficient for the functioning of the system for at least
20 minutes needed to save the results of analyzing and processing.
2. For low noise and reliable system action the monitor, power units of cameras should be
connected to an electric network through the special sockets having additional ground
contact (the socket of a class 1).
3. For reliable maintenance system the equipment included in complex and the equipment,
taking place in direct near should be certificated on electromagnetic compatibility according
to requirements.
Light exposure requirements
1. Natural illumination of object can be used only if speed of natural light exposure changes of
object does not exceed 1 Lx/s.
2. Illumination of object by fluorescent lamps with illumination in a range 400 - 600 Lx in a
plane of object is preferable.
3. When the system operated in continuous mode the lighting in indoor all time should be
from 400 to 600 lux.
Camera vibration requirements
1. The television camera used for surveillance and-or object on which the camera is
established, should be motionless.
2. Allowable vibration speed of television camera not more than 0,1 mm/sec in the range (0,1-
50) Hz.
Settings VibraImage recommendations
For correct results, you must minimize:
Light sources, fixtures and bright surfaces, windows, etc.
Window, which gets the image from the streets.
Glass surfaces such as walls, which change with the lighting system in the room or on
the street lighting can act as «mirrors».
Light sources with variable lighting (flickering, flashing, etc.) or lighting systems,
which are moved mechanically (subject to vibrations from external factors).
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
12
Light sources with a unidirectional light, i.e, a person must uniform illuminated from all
sides.
Outside people influence,
The moving objects, sliding doors, people passing by, etc.
Hardware Requirements
1. The resolution of the TV camera should be at least 640x480 pixels, and the rate of input
video frames to a computer for at least (25-30) f/s.
2. Is recommended to use the TV cameras with low noise.
3. After starting the program VibraImage CPU load should not exceed 80 %.
4. The computer's hardware must provide performance rate for real time processing at least 25
f/s captured from the television camera.
Factors affecting the quality of vibraimage
The following factors are taken into account for the correct vibraimage processing:
1. An object (person) has to be well and evenly lit, and normal (black and white or color)
image of a man should be clear and contrasting human face in the frame should be no
smaller than 200 pixels.
2. The person must be in its natural state, when unconscious processes, especially the
vestibular system, determine its movements. It is necessary to exclude the presence of
additional mechanical contact sources (for example, a man leaned against a certain subject,
leaned on the table and leaned his head by hand).
3. Vibraimage Micro mode is designed for the visualization of vibration only one object in the
frame, so the live objects that are close to the main object of study, can significantly affect
and distort the vibraimage of the main subject.
4. There is a certain delay between the current psychophysiological state and vibraimage. The
value of this delay is mainly determined by the selected accumulation time. For example,
when the real system performance 25 f/s and the selected time N=100 frame, the objective
vibration aura of a person can be displayed on the screen is not earlier than 4 seconds after
the person in front of the camera. Therefore, a person must remain in the field of system
camera view for at least 10 seconds.

4. After correct connecting of camera, the image appears on the screen.
5. Perform video camera settings (see. Fig 2.3).
6. Perform quality control of videoimage (see. Fig 2.4) and, if it necessary, eliminate the causes
of low-quality video.
7. Select the directories for recording video information and log files.
8. Get started in accordance with the program description.
2.3.1 Video quality auto checking function
The VibraImage program has built-in automatic quality control function image quality
control during the test. Since the calculation of human reaction using the video image, the quality
control for the processed video is necessary to obtain a correct test result. Error message and the
low quality of video will appear on top of the QT windows (fig. 2.4), but only if the «Quality test»
mode in «S» information panel is switch on.
Program gives error indication if the image quality is lower than standard vibraimage
requests:
Error 1 – indicates when facial image is lower than necessary. For cancel this error is need
to move checked person near to camera or start zoom function on camera.
Error 2 – indicates when camera noise level is higher than necessary. The reason of this
error could be low illumination, incorrect camera settings or camera vibration.
Error 3 – indicates when computer input frame rate is lower than necessary. Requested norm
for processed frame rate is more than 24 f/s. This errors indication was done for deleting
unqualified staff influence during results control.

18
Fig. 2.4. Error message 1 – low quality of image
The size of the person's head image in the picture elements (pixels), which determines the
accuracy of recorded vibrations, requires constant monitoring during testing. When tested with a
video image analysis there are no severe restrictions on the movement of the test person, as required
by the contact method. This person feels natural, which increases the accuracy of test results.
However, the natural behavior can lead to the fact that during the test response deviates
from the camera and the size of the human head image becomes less than required. To resolve this
issue vibraimage system constantly monitors a person's head size of the image and displays an error
message (1) in the window «QT» in the case of reducing the size below the limit. In addition,
vibraimage program includes a permanent face detection algorithm, which ensures elimination of
errors from a lack of a real image of the person in the frame during testing.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
19
Fig. 2.5. Error message 2 – low illumination
Temporary noise signal from the video camera includes a video camera noise and
illumination instability and can significantly affect the test results. In this case, at the slightest noise
level exceeds the specified threshold, the system automatically displays an error message (2) in
«QT» window (see. Fig. 2.5).
Despite the fact that the television camera may transmit to 30 f/s with the set resolution, it
does not guarantee that the computer receives and processes the incoming video data in real time.
And any deviation from the information processing in real time resulting in a loss of information
and hence reduce the reliability of the test. By reducing the actual input frames frequencies and
processing frequencies below the set limit, the system automatically displays a warning error (3).
Window «Quality Test» (QT) indicates the time in %, for which the image quality of
100 %. When the quality test indicates 43 % means that only 43 % of the testing time have no
errors, and the 57 % of test time the image quality contained 1, 2 or 3 errors.
Note, before the start of the test should ensure that the program processed the image of a
human without errors.

After a choice of the «Video capture filter...» the window «Settings» will open. Settings
window differs depends on camera type. When adjusting the camera settings, you must fulfill the
following general requirements:
The «Brightness», « Contrast » and others parameters should be configured so that
the image of the object was the maximum contrast.
Switch on «Flicker» mode for setting lighting power line frequency (repayment
flicker), in most countries it is 50 Hz.
If your camera supports, then switch on the black-and- white image «B / W mode».
If the camera works only in color mode, is recommended to set «Saturation»
parameter to minimum value.
Depending on the experimental conditions and light to use automatic or manual
setting «Exposure» parameter. If constant lighting, it is recommended to use the
manual adjustment. If changes (for example, an object depends on the lighting street
lighting), it is better to use the automatic adjustment mode setting.
Parameters «Zoom» and «Focus» is recommended to use in the manual mode and
change their values not due to electronic image processing, but by approaching/
removing the camera from the object.

additional complex T1 - T10 parameters having psychophysiological sense. Complex vibraimage
parameters represent psychophysiological information about a person and informative component
of these options depends not only on calculation algorithms, but also depends on targets and
conditions of vibraimage system applications. For example, under different test conditions (state of
rest, stress, movement…), the same parameters can provide information about the physiological and
psychological state of a person, as well as the suspicious level of person.
The set of parameters T1-T10 is selected so that a maximum information records all
micromotion human head. In this case, the name of each parameter Ti characterizes various
physiological characteristics depending on the vibraimage system application. The name is not
primary characteristics for said vibraimage parameter, it can be considered as suppositive and the
formula by which this parameter is determined has more correct sense. Despite the suppositive
names, given description uses the following (historically developed) range of parameters:

4 The basic modes of the VibraImage system
VibraImage system has 3 basic operation mode:
1. Micro mode – it is intended for supervision, research and the analysis psycho emotional
conditions of the one person in the frame.
2. Macro mode – it is intended for supervision, research and the analysis psycho emotional
conditions of the people in crowd.
3. «Lie detector» or LD mode - it is intended for lie detection of the one person in the
frame center.
The user can choose a system operating mode, having set options by default, selecting the
appropriate line in the sub-menu «Settings» - «Default» (see fig. 4.1).
Fig. 4.1 Select «micro» mode
When you select one of the basic modes of operation (micro, macro or lie detection) and
load its default settings, the system automatically displays only the necessary window (fig. 4.2).

Fig. 4.2. «Micro» mode loading
4.1 Micro mode. Emotions (personality traits) definition
The main targets of the MICRO mode («M») are receiving significant psychoemotional and
psychophysiological personality portrait and carrying out functional diagnostics test person. It is
possible to use MICRO mode for security system applications and identify suspicious people on the
protected objects. Usually, for security system applications MICRO mode is using without M
button, and detection of the suspicious level (Suspect indicator) is based on calculating T4
parameter in real time mode.
It is known that the psychoemotional and psychophysiological state of a person is constantly
changing under the influence of external and internal factors. In the «M» mode are measured
average values of psychophysiological parameters T1-T10 (emotion10print) for the fixed time
period and their deviation from the established norms.
There are different science opinions about emotions, behavior and personality traits. General
description about these points is described in Wikipedia and science publications, see
https://en.wikipedia.org/wiki/Emotion
https://en.wikipedia.org/wiki/Behavior
https://en.wikipedia.org/wiki/Personality_psychology
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
86
Elsys Corp. suggested own concept about personality and mental features which includes
several main points:
1. Preferable math methods than words for personality traits indication, because math
formula gives only one sense for indication. The word has different interpretation because different
users give different sense to the same word.
2. The list with formulas for indication of every vibraimage emotion 10print algorithm is
described in VibraStat program manual. It is not necessary to obstruct the current Manual by unused
for typical user information.
3. For T1-T10 parameters was selected 4 main parameters for indication positive emotions
(personality traits), 4 main parameters for indication negative emotions (personality traits) and 2
main parameters for indication of physiological characteristics. In our understanding we selected
the most important and informative parameters for selected groups and used the terms based on
current psychology science level.
4. From vibraimage point of view we suggested the different math methods for head
vibration calculation because the main math task of vibraimage is to detect all parameters of head
vibration so as we supposed that head vibrations reflect all personality traits and emotions.
5. Of course the list of selected parameters is not finished. Based on customers’ requests is
possible to extend this list and add some parameters which are actual like sleepiness level or
tiredness etc. The most part of a new emotional parameters could be calculate based on existing
emotion10print (T1-T10) after additional reseaches and statistics capturing.
The analysis determined the expectation M, standard deviation S, and variation V=S/M for
the following psychophysiological parameters measured in («M») mode:
Т1 – Aggression (Р7)
This parameter is determined by the frequency histogram and represents the maximum
allocation of the frequency and SD vibration frequency of the human face (fig. 4.3). The higher
value of the maximum distribution and higher SD value gives the greater value of the parameter T1.
a) b)
Fig. 4.3 Agression; a) T1= 18 %, b) T1= 60 %
Т2 – Stress (Р6)
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
87
Parameter is determined by degree of the external vibraimage (vibra-aura) asymmetry,
means asymmetry of micromovements from the left and right parts of the person’s head (fig.4.4).
The great difference in amplitude and frequency movements for the left and right parts of the face
(head) characterizes the increased T2 parameter level.
a) b)

VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
88
Т3 – Tension/Anxiety (F5X)
Parameter is determined by the relation of high-frequency part of a range of vibrations to the
general power in a range of micromovements frequency for human head (fig.4.5). High value of
high-frequency vibrations density characterizes high value of the T3 parameter.
a) b)
Fig. 4.5 Tension; а) T3 = 28 %, b) T3 = 48 %
Т4 – Suspect (Р19)
The parameter is determined as the sum average of the first three conditionally negative
emotions (T1, T2, T3) and characterizes the general level of conditionally negative emotions in a
person status (fig.4.6).
a) b)
Fig. 4.6 Suspect; a) T4 = 20 %, b) T4 = 65 %
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
89
Т5 – Balance (Р16)
The parameter is determined by the frequency histogram and characterizes the level of
similarity of the current frequency histogram to the Gaussian distribution law (fig.4.7). The high
level of frequency histogram similarity to the normal law is characterized by a high level of
balance, and significant deviation from the Gaussian distribution is characterized by a low level of
the parameter T5.
a) b)
Fig. 4.7 Balance; a) Т5 = 10 %, b) Т5 = 80 %
Т6 – Charm (Р17)
The parameter is determined by the symmetry (left-right) of the head and face
micromovements, the maximum symmetry of movements (including frequency and amplitude)
represents a high level of charm T6 (fig.4.8).
a) b)
Fig. 4.8 Charm; a) Т6 = 40 %, b) Т6 = 85 %

90
Т7 – Energy (Р8)
The parameter is determined by the frequency histogram and characterizes the difference of
the maximum density of the vibration frequency and vibration frequency SD for the face and human
head (fig.4.9). The higher value of the maximum density and lower SD or variation of vibration
gives the higher value of energy T7.
a) b)
Fig. 4.9 Energy; a) Т7 = 3 %, b) Т7 = 70 %
Т8 – Selfregulation (Р18)
The parameter is determined as the sum average for conditionally positive emotions (T5,
T6) and characterizes the general level of conditionally positive person emotions at the
measurement time (fig.4.10).
a) b)
Fig. 4.10 Selfregulation; а) Т8 = 30 %, b) Т8 = 80 %
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
91
Т9 – Inhibition (F6)
It has a real physical dimension (time in seconds) and characterizes the minimum time of the
person reaction for the shown event (the stimulus). The value of the parameter T1 = 0,1 means that
the reaction time is 0,1 s (fig.4.11). The greater the reaction time corresponds to a higher level of
inhibition.
a) b)
Fig. 4.11 Inhibition; a) Т9 = 12 %, b) Т9 = 25 %
Т10 – Neuroticism (F9)
The parameter characterizes the SD measured value of the inhibition level (T9) at the
measurement time (default 60 seconds) (fig.4.12). High level for inhibition SD of
psychophysiological state characterized by instability and indicates high level of neuroticism T10.

Note:
The set of parameters T1-T10 is selected for capturing of the maximum information content
for human head micromotion. At the same time the name of each Ti parameter can characterize
different physiological characteristics, depending on the application of the vibraimage system. The
primary characteristic for each parameter is not his name, the name can be considered secondary,
but only math formula (equation) for psychophysiological parameter calculation is primary.
Mathematical formulas, on which a calculation of parameters T1 - T10 are shown in the description
of the program of statistical processing of the measurement results (VibraStat).
Note:
1. Every from T1-T10 psychophysiological parameters measured by vibraimage system
are specified to range 0 - 1 (0 - 100) % using fixed coefficients experimentally selected.
2. Mathematical formula by which measured psychophysiological parameter is
determined is primary, and a code name (for example, Agression) is secondary.
Psychophysiological meaning of each parameter T1-T10 may be varied depending on the
experimental conditions.
3. The set of measured parameters T1-T10 determines the total psychophysiological
(psychosomatic, functional) status of a person based on the integral coefficient K.
Note:
This description is valid for the parameters to the default settings of the system and perform
basic rules for getting vibraimage:
uniformity and stability of the lighting;
use of low-noise television cameras;
frontal location of the object in front of the camera;
maximum «inscribing» the subject's face in the monitor;
mechanical stability of video camera.
4.1.1 «M» mode of information panel
In a «M» mode an information column (fig. 4.13) allows to control average for the period
parameters value of psycho-emotional person conditions and their deviation from the established
norm. The basic applicability of the given mode is use of vibraimage system for medical
diagnostics and psychological researches. Start of the beginning of information accumulation is
made by a choice of item «Measurement» of the menu «Action» or pressing of the toolbar button
. Value of the averaging period is set in seconds in a field «Duration». After start of a
accumulation and averaging mode in the top of an information column there is a running line

4.2 Macro mode. The suspicious people detection in crowd.
VibraImage system allows controlling macromovements (macrovibrations) as
microvibration. Macromovements analysis uses the same principles as the control of micro-
movements, at the same time it allows to monitor the status of the people in the crowd. If
micromovements of human head can not be seen without a technical system, it was well known that
movements and psychomotorics reflect emotional state of person since such behavioral reactions
are well observed by psychologists and profilers. However, visual inspection of the movements is
really subjectivity, at the time, as the vibraimage system macromovements control completely
objective and is determined by the calculation formulas and the selected system configuration. The
optimal camera location and the choice of checking place are determined with considering the lens
parameters, the distance from the camera to the object and the amplitude of motion of the object.
When choosing the location of the TV camera relative to the envestigated group of people is need to
use the following recommendations:
The maximum display of human on the frame is preferable, and the camera should not
be unduly moved from the envestigated group.
People in the envestigated group must be approximately on the same distance from the
television camera.
In the analysis of the emotional state should use an equivalent comparison principle, the
correct is a comparison of people making near the same motion, for example, feed the ticket
compared with the person submitting the ticket, the person transposing luggage compare with a
person committing the same act, etc.
Note, that in order to improve the accuracy of the human state measurement, reccomends to
control its movement in maximum details, therefore, observe the minimum number of people in the
frame. Question of the measurement accuracy for the psychophysiological state should be decided
separately for every controlled object. In this case, for more accuracy it is recommended to use
personal control in MICRO mode for suspicious people detection in the high important places.
4.2.1 «Macro» mode parameters
Load basic MACRO modes parameters of operation is carried out using a submenu
«Settings» - «Defaults». When one of the basic modes of operation (micro, macro or lie detection)
select and load its default settings, the system automatically displays only the necessary window
mode (fig. 4.19). To work in the «Macro» are necessary images window, «Suspect level» window,
which will display the value of danger level, and «Image capture» window detected potentially
dangerous people photos.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
100
Fig. 4.19. Macro mode windows
Figures 4.20, 4.21 shows a comparison of the basic settings are set automatically when you
select Micro and Macro mode :
When micromotion control system also monitors the status of the person at the three
different accumulation times (from 0,1 to 20 seconds), characterized by the number of frames N =
2, 10, 100. Recommended accumulation amount frames in macro mode comprise N = 5, 10 and 15
frames that the input frequency 15 f/s, corresponding 0,3-0,6-1,0 second. Comparison of the number
of movements made by a person in a given time, gives a clear picture of the psychoemotional state
of a person. If a person is excited or aggressive state, it makes a lot of movement than those who are
at rest, and it stands out vibraimage color coloring compared to other people.
«Palette threshold» is set at the control macromovements above (L = 150) than in the
control micromotion (L = 2).
Frequency of «base processing» under the control macromovements set
substantially higher than in the control micro-movements, to the 15f/s instead of 5. This is due to
the fact that when micromovements no point in increasing the sampling rate, as TV system noise
does not allow stable fixing micro-movements with a higher frequency. Another thing
macromovements control - movement of the hands, feet or body when walking, turning or other
fixed macromovements confident enough television camera, and significantly higher than the noise
level.
In macromovements analysis mode to increase the computing capacity of a PC, the
calculations are disabled several parameters and the «Disable» information column «S».

102
Especially for setting display modes when using the Macro mode in the information column
«S» introduced a number of parameters:
Macro section:
Маcro mode - If «Macro mode = Yes» than danger level calculation is made on the
basis of values of parameters Р13, Р14, Р15 (the description of parameters is see lower). In
«Micro» mode danger level calculation is made on the basis of the analysis of values of
aggression (Р7), stress (Р6) and tension parameters.
Level L - sets a palette threshold at danger level calculation. Vibraimage points
which brightness less than the specified threshold, are considered «black» and are not used
at calculation of a danger level. The vibraimage point is considered active, if its brightness
more than the set threshold«Level L». Parameter Р15 defines the relation between the area
of «active» vibraimage points to the area of all frame. Parameter Р13 characterizes shift of
the histogram to the right in area of high frequencies. So that parameter defines primary
color of «active» points of vibraimage.
Level S - defining the area of «active» vibraimage points. If the area of points (in
%), which value of brightness is more than value «Level L», is less than value «Level S»,
than danger level value displayed in status window equally 0. So, if in the frame it is not a
lot of «active» points, the level of danger is not calculated.Parameter Р14 defines in %
excess of the area of active vibraimage points above the set threshold of «active point»
«Level S». So, if the number of «active» points grows, value of this parameter too grows
also a level of danger increase.
Aura mode - automatic cut output vibration aura when working in macro mode.
Macro mode + - when mode is switch, the danger level is considered for each
individual person in the frame. In off mode - the danger level is averaged over the entire
frame. «Macro mode+»= NO recommended when working of face detection algorithms is
not effective in this particular case.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
103
Fig. 4.22. Macro mode basic settings.
«Alerts» section:
«Critical level» – Sets a threshold of «danger level» at which excess the person is
considered «dangerous».
«Auto capture image (s)» – If set «non zero» value, than the image of «dangerous»
object at his detection will be automatically save in an external file. The chosen value of the
given parameter determines in seconds the period of saving the pictures in a file.
Simultaneously the image «dangerous» will be displayed in «Image capture» windows.
«Show N image» – If set value N distinct from 0 in «Image capture» window will
be displayed at once N images of the «dangerous » people which have been found out for
the specified interval «Auto capture image (s)». If set value N = 1 - that for the specified
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
104
interval in «Image capture» will be displayed only one image, and we can pass other
«dangerous» person!
«Auto capture image (s)» – Value of this parameter (other than 0) specifies the
number of seconds between saving images to a file and display them in «Image capture»
window.
«Area threshold %» and «Area level %» – These settings is recommended only for
experienced program users. Area and significance (level) coefficient factor are given in %
and is introduced to take into account the factor of small area of moving objects relative to
the area of the whole frame when calculating the danger level.
4.2.2 Face detection mode
Switching on the «Face detection» is made in the same section of the «S» information panel
(see fig. 4.23).
Рис 4.23. Macro mode. Face detection is switch on
The parameter «Detection quality» defines quality of persons face capture. 1 – capture only
one large person in the frame (loading of the processor is minimal), 4 – search of all face (even
small) persons in the frame (loading of the processor is maximal).
Parameter «Scale 1:X» sets picture compression ratio before process of search of persons.
By default, value 2.0, i.e. video of a format 640х480 will be transformed by the program to a format
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
105
320х240. Compression of a format is necessary for reduction of loading of the central processor in
case of simultaneous increase in speed of the main processing (base processing). In case of value 0
compression isn't made. The lower the compression, the more CPU usage. The greater the
compression, the lower face recognition algorithm works.
Parameters «Mines size» and «Max size» set the sizes of rectangular (in pixels) for persons
face searching. The given parameter is necessary for set depending on concrete medium-sized
people on the computer screen.
The parameter «Config» is intended for loading new algorithms of persons search. At
installation of Vibraimage program on your computer will be created the subdirectory
«…\VibraImage10\Ocv\» in which files of various algorithms of persons search settle down. For
loading new algorithm, it is necessary to execute the following actions:
1. In «File» menu select item «Open». Then open folder \VibraImage10\Ocv\ and choose
new algorithm for calculation.
2. In line «Config» appear path to selected file.
Note, that each algorithm at work require different amounts of computer resources and
implementing different quality capture individuals. When choosing the algorithm is recommended
not to exceed the CPU utilization of more than 70%. By default, when you install the system
VibraImage very little resource-loaded algorithm ocv_face.xml. For fast computers recommended
load frontalface_default.xml algorithm. But, note, the choice of the algorithm and the quality of the
capture of persons recommended when setting up the system after it is installed in a particular
location.
If parameter «Draw» = No – not draw rectangle around face. If «Draw» = Yes – draw
rectangle around «more danger» single person, «Draw» = All – draw rectangle for all person in
frame:.
For non-danger person rectangle draw green color, but if person suspect level more than
«Critical level», than rectangle draw red color (see fig. 4.24).
If a potentially «dangerous» man except the red outline appears around the head and a
red outline around the body, this person requires more attention from the security
services, because the system repeatedly fix it increased the suspect level.

Attention!!! if you are changing system settings when working in the «Macro» mode, then
you need to constantly monitor the following settings:
1. After start of Vibraimage program and person vibraimage displaying on the screen
loading of the computer central processor power must be less than 60 %.
2. Speed of input frame processing. Speed of «fast processing» should be not less than
25 frame per second at resolution not less 640х480 pixels. Speed of «base processing»
should be not less than 14-15 f/s.
If you change the «macro» mode settings and specified speed is not respected, it is necessary
to set other parameters that require less computer resources.
Note, when a detailed system configuration at a particular place of its installation may
require advanced settings «Area threshold», «Area level», «Level S» and « Stab. X, Y ».

4.3 LD mode. Lie detection
The VibraImage program of psycho physiological lie detection allows revealing verbal and
nonverbal lie in the automatic, automated and manual modes. The program allows fixing and
comparing psycho physiological parameters of the person during the various moments of time at
use of various modern techniques of interrogation. All means existing now lie detector register
changes various psycho physiological parameters of the person, thus it is considered, and that
essential change psycho physiological parameters is observed when the person worries, is excited
and speaks a lie. In a still condition of person his psycho physiological parameters and emotions
vary less considerably in time, hence, having compared a known still condition with the answer
interesting us it is possible to define, when the person speaks the truth and when speaks lie.
The program allows to fix and compare psycho physiological parameters of the person
during the various moments of time. VibraImage system makes measurement and the analysis in
time more than 40 independent parameters describing an emotional condition of the person. The
standard method of definition of lie is based on an estimation of emotional reaction of the person on
the «put» question.
The standard method of lie detection is based on an estimation of emotional reaction of the
person on the put question. In an operating time the operator marks on graph CQ questions (Control
Question), RQ questions (Relevant Question) and GQ questions (General Question), pressing on the
, , on the toolbar at time of the given questions. After the ending same buttons
of the test the operator can check results of work in a special created file.
4.3.1 Before starting LD mode
For correct lie detection by Vibraimage system is recommended to take into account the
following factors and conditions:
1. The image of the person should be high quality, the maximal facial size preferable
and face position must be in the center of the screen. For camera horizontal
resolution across 640 pixels the person face should be not less than 200 pixels.
2. The object (person) should be well and stable illuminated also (black-and-white-
preferable, or color) the image of the person should be precise and contrast. As lie
detection depends on detection of the microvibrations and the object
micromovements fixed in reflected from object light, therefore poor light exposure
of object can increase error rates.
Natural illumination of object can be used if speed of natural light changes does not
exceed 1 lux/sec. Illumination of object by fluorescent lamps with illumination in the
range 400 - 600 Lux in object plane is preferable.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
109
3. In a video camera options it is necessary to switch on a mode of fluorescent lamps
noise suppression (flicker mode 50Hz and 60Hz).
4. In camera options it is recommended to use black-and-white image mode.
5. Presence of the other people, taking place in the frame near to the researched object,
can influence and increase error rates of lie detection.
6. The video camera used for surveillance, and/or object on which the camera is fixed,
should be motionless and have no vibrations. The vibration or movement of camera
can increase error rates of lie detection
7. Speed of input frame from the camera should be not less than 25-30 frame per
second at resolution not less 640х480 pixels.
8. After start of Vibraimage program and person vibraimage displaying on the screen
loading of the computer central processor power must be less than 60 %.
9. The set of a microphone is recommended to use external, not built-in in the camera
or notebook.
10. At work with videofiles it is recommended to use files in length of 5-10 minutes and
for exact lie diagnostics it is recommended to analyze the same file repeatedly some
times.
11. Press button before next lie detection of the same file. button works as
reset and stabilized detection results. Double click on this button fixed graphs time
equal to the video file period.
Note
At repeated viewing the same videofile the deviation in repeated values the same parameters
up to 5 % is acceptable because live video is the same as live object error rate less than 5% is
normal. For stable work in a «Lie detector» mode is recommended use personal computer
CoreDuo2 3GHz (not less than 4Gb RAM) or more powerful. At such computer speed of input
frame from the camera should be equal speed of fast parameters processing FPS_in=FPS_fast> 25-
30 frame/s.
4.3.2 Switch on LD mode
Load basic LD modes parameters of operation is carried out using a submenu «Settings»-
«Defaults». When one of the basic modes of operation (micro, macro or lie detection) select and
load its default settings, the system automatically displays only the necessary window mode (fig.
4.25). To work in the «LD» mode are necessary images window, «QT» image quality window,
«LDr» lie level window, «Graph» window with changing main parameter, and «LD question»
window for show questionnaires question.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
110
Window «Quality Test» (QT) indicates the time in %, for which the image quality of
100 %. When the quality test indicates 92% means that only 92% of the testing time have no errors,
and the 57 % of test time the image quality contained 1, 2 or 3 errors.
Note, before the start of the LD detection should ensure that the program processed the
image of a human without errors and work is allowable only at quality more than 80 %.
Fig. 4.25. «LD» mode settings load
Next, using the toolbar button , or via the submenu «Presets» menu «View» (see
fig. 4.26) need to switch on the LD mode image display.

111
Fig. 4.26. System ready to LD mode
Attention, at work in a LD mode is recommended to supervise under graphs of change in
time following psycho physiological parameters describing all types of impellent activity: А1 fast,
F3, F6, S2, P2, P5 and Р20.
A1 (fast) – shows maximum fast reaction of person for question or situation, so it changes
before any other VI parameters, but goes down also immediately as it changed. This parameters
shows macro movement and sometimes used for deleting artifacts from the lie detection process.
F3 – shows general mental energy level of examinee, in default settings this parameter
calculates for time period of 20 seconds, so it is slowly changing parameter reflects psycho
physiological state. High level of this parameter indicates high level of exciting, aggression or
activity so it could be correlated with lie.
F6 – shows inhibition of person and also correlated with respiratory tracing or breathing
activity, because it is physiology linked with inhibition process.
S2 – shows asymmetrical of movements in middle time (2 sec) period, so it includes
left/right hemisphere activity components and it high changes usually indicates lie.
P2 – shows Mean-Square-Deviation (MSD) of frequency histogram and low meaning of this
parameter usually indicates normal state, so high meaning of this parameter could be correlated
with lie.
P5 – indicates Lie level auto calculated for selected parameters, in Default settings for Lie
indication need to have significant changes at least in 8 vibraimage parameters, typically in Lie
detection system registers significant changes in 12 or more parameters, given in Lie Report.
P20 – Quantity indicator of a degree of change psycho physiological parameters in view of
various factors of the importance of measured parameters since the part of parameters is
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
112
accelerated, and others are slowed down during one reaction. Parameter Р20 is defined at the
moment of P5 maximum and display in «LDr» window.
When working with graphics, special attention should be paid to signal changes in the graph
of parameter P5 (lie), which define the most «suspicious» moments in human behavior. Each
question and answer (preferably separated by a time interval of not less than 10 seconds) is
characterized by a level change phychophysiological parameters tested person. This level is
characterized by two integral indicators - the level P5 (see fig. 4.59.) and parameter P20 in the
window «LDr», which provides a quantitative assessment of human responses to the question. The
higher this parameter, the more likely lies in the response.
4.3.3 LD working mode
Select the method of of the beginning lie calculating [LD mode] is made in the «ST»
information column in field «LD mode» (see fig. 4.27).
Fig. 4.27. LD mode settings.
The system uses the following ways to start the lie level calculation:
1) Audio - lie level calculation is performed when the input audio signal exceeds the
threshold, and stops when the audio signal level becomes less than the set threshold. On
graph at the start of data collection displays vertical green line, the time of completion -
a vertical red line.
This mode is recommended as the primary when working with a lie detector.
2) Manual - the accumulation of the preliminary information is available at the «Base
periods». Calculation of a lie level is made only after selecting the «Start LD block»
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
113
item in menu «Actions» (or corresponding toolbar item). To complete the
calculation interval of lie detection, you must repress the same button or choose the same
menu item. Time of lie start calculation is marked by a vertical green line, calculate the
end - red.
Lie detection in the manual mode are usually used, if the quality of live or recorded
sound is unsatisfactory and can not be on the level of sound to separate the questions and
answers of the test person from outside noise.
3) Auto - calculation lie level is made constant, the current values of the parameters are
compared with the values accumulated in the preceding period.
When operating in lie detecting mode in an «S» information column (see fig. 4.27) is set the
interval «Base period» (in seconds) during which the system collects data about the object under
study, accumulates the information to determine the maximum and minimum current values
parameters to then at «lie detection» during the «Stat periods» define «abnormal» change the
values of the individual parameters of the object. If the value of the parameter during the «Stat
period» exceeds the set limit, then it parameter is taken into account when lie level calculating with
a certain coefficient (weight (Rate) of this parameter).
The base case «Base period» immediately precedes the moment of the beginning of the
analysis lies. But the system provides the ability to collect initial information about the object at any
time. When you select a item «Compare»=Capture will be made beginning start the sampling
interval at an arbitrary time. To complete the collection interval, you must change the settings
«Compare» value.
Now when you lie detection analysis the state of the object will be compared with the
information stored in previous time in one of two ways:
«Compare» = Off - at the lie analysis, as a test, using the interval «Base period»
immediately before the start of lie detection.
«Compare» = On - in the lie analysis, as test, the interval «Capture period», which was
prepared preliminary.
4.3.4 Additional settings in «S» information panel
1. For stable work in a «Lie detection» mode in section «Filters» of the «S» information
panel it is necessary to set parameter «FPS filter» = YES. The parameter «FPS filter» provides
stability of input video frame stream frequency due to resources of a computer. If the parameter
«FPS filter» = No, than parameter «Downrate» in «S» information panel sets factor of division of
input frame frequency FPS_in for all processing mode (base and fast). If the parameter
«FPS filter» = Yes, than parameter «Downrate» sets factor of division of input frame frequency
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
114
only for base processing mode. If «Downrate» = 0, than division factor calculated by system
automatically. If input video frame stream frequency not stability, than additional parameter
«Stream errors» in «VI» information panel displayed quantity of entrance frequency «failures».
2. Additional parameter «Audio sens. s.» in an «S» information column sets in seconds,
how many after the person answer ending still to continue to analyze his condition.
3. The parameter «Lie threshold » in an «S» information column sets in % a threshold for
the indicator of a lie level in view of all designed parameters and their «weight». At excess
settlement value of this threshold «lie level» is registered and displayed.
4. Each person differently reacts to lie by virtue of the psychophysiological features. The
part of people when lie, «worries» also their reaction (value of parameter Р5-lie) on the «important»
questions (RQ questions) exceeds reaction to control questions (CQ questions), and the system
registers a condition of lie (DI). For such people parameter «Opposite mode» = NO (it is a mode
by default). And the part of people - on the contrary, internally «is clamped (strains)» and their
reaction (value of parameter Р5-lie) on the «important» questions (RQ questions) less reactions to
control questions (CQ questions), and the system does not register a condition of lie (NDI). For
such cases for increase of reliability of lie detection results the parameter «Opposite mode» = Yes
(it is a mode is recommended for experienced users).
5. Note, VibraImage system requests correct adjustment of input audio signal (procedure of
adjustment see above). The moment when the person starts to speak, is used by system for the
analysis start of the data in Audio mode. Vibraimage parameters during speaking (Stat period) are
compared to the data received earlier (Base period), for example, when the person was silent or
neutral answer questions.
Therefore it is necessary to adjust preliminary an «Audio level» so that the surrounding
level of a sound was below threshold, and the level of a sound at the task of a question and
reception of the answer was higher threshold.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
115
Fig. 4.28. Audio level adjusting
To adjust sound level is necessary in an «VI» information column to measure the sound
level (fig. 4.28) for the two states: «the silence in the room» and «the sound of the human voice to
the camera». Then in the settings of «lie detection» in the «S» information column set the
parameter «Audio level» (fig. 4.28) so that its value was in the middle position between the
minimum value of the input signal that corresponds to the silence in the room, and a maximum
value, which corresponds to the sound voice man facing the camera.
Values of system options recommended (by default) for work in a lie detection mode:
Stat period = 10 s
Base period = 5 s
Lie Threshold = 0 %
Opposite mode = No
Audio sens = 2 s
N = 100

4.3.5 Settings in «LD» information panel
If you have enough experience works with the lie detector, you can manually configure the
numerical values of the parameters A1 to P29, opening the appropriate «LD» information panel (see
fig. 4.29).
Fig. 4.29. LD mode of information panel
For each parameters displays the following numerical values:
V – Current parameter value;
cMin – The minimal value of parameter during the «Stat» period;
cMax – The maximal value of parameter during the «Stat» period;
bMin – The average basic minimal value of parameter for a normal condition of
the person during «Base» period;
bMax – The average basic maximal value of parameter for a normal condition of
the person during «Base» period.
For each parameters set following numerical values, which using in Lie detector calculation:
Calculate Yes - this parameter using in LD level calculation, No - not using.
R1V «Weight» of parameter (Rate1) if its current value became more than
the set base maximum bMax OR became less than the set base
minimum bMin. Use in Р5 parameter calculation.
R2V «Weight» of parameter (Rate2) if its current value became more than
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
117
the set base maximum bMax AND became less than the set base
minimum bMin. Use in Р5 parameter calculation.
R1C «Weight» of parameter (Rate1) if its current value became more than
the set base maximum bMax OR became less than the set base
minimum bMin. Use in Р20 parameter calculation.
R2C «Weight» of parameter (Rate2) if its current value became more than
the set base maximum bMax AND became less than the set base
minimum bMin. Use in Р20 parameter calculation.
Level In % determines on how many value of parameter should exceed the
set limits that the system «considered» this change.
The following are examples which illustrate the principle of collecting information. Fig 4.30
has no difference in the «threshold» values of S2 in intervals «Stat period» and «Base period. Fig
4.31 during the interval of definition lies (Stat period) value S2 has exceeded the maximum
threshold.

4.3.6 Backster’s test
The basis of lie detection is a technical comparison of the principle of psychophysiological
reactions responses zones (introduced Clive Backster), it is quite easy to understand and allows
each person to accurately determine the truth and lie even with minimal experience in working with
VibraImage system.
Principals of comparative testing and averaging for responses of question-answer zones,
coined in the 60th years of XX century by Cleve Backster
(http://www.backster.net/images/accuracy.pdf), gave requested high accuracy for
psychophysiological detection of deception and have done lie detector the reliable instrument in
expert hands. The comparative zones are based on the fixed structure of question-answer testing,
including general, comparative and relevant questions in one test. So fixed test structure allows
combine analyzing of response to several similar questions, so it is possible to calculate average
response to several control questions and separately calculates average response to several relevant
questions. This testing structure gives more accuracy for any measurement, so it is acceptable also
for lie detection, too. Standard lie detection test structure includes 9-14 questions, one of these
questions relevant (most important) is presented by several times (during one test), because was
proved that during one test is correct to present the only one relevant question. Several relevant
questions in one test give more errors, because examinee could concentrate only on one question
during the test.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
119
Let’s consider the test structure on the simple actual test sample: You are interesting where
your partner was at night, when he tells that was working in office. In this case the question
«Really, were you in the office last night?» is relevant question and the main important question of
this test. All test must include several questions for replying one meaning answers as Yes or No,
like the suggested sample:
1. Did you have breakfast yesterday, as usual?
2. Was the cold weather on the morning street?
3. Did you tell lie to your friends?
4. Did you work in office this night?
5. Let’s go to cinema this weekend?
6. Did you ever tell lie to me or my family?
7. Really you were in office this night?
8. Did you take your purse from home at this morning?
9. Did you steal something before?
10. Is it true, that you were working this night?
General (blue) questions (GQ) have diverted meaning and have not influence to calculation
result, but they are necessary for reducing concentration attention of examinee on the relevant
questions. Response to the control (green) question (CQ) is very important to the test calculation,
control question usually asked about past criminals, which are happened in everybody life. The
verbal answer on control question is not so important (Yes or No), more important is
psychophysiological response corresponding to this reply. If quantitative average response to
control questions is more than analogical quantitative average response to the relevant (red)
questions (RQ) that means person tells true. If quantitative average response to relevant questions
(RQ) is more than analogical quantitative average response to the control questions (CQ), that
means person tells lie.
4.3.7 Lie detector with questionnaires
Program VibraImage has a special type series of thematic questionnaires intended for human
psychophysiological person testing, such as passing an interview before obtaining a credit.
You can select an existing questionnaire suitable for you («Loyalty», «Alcohol», «credit»,
«bribe», «Family» and others.) or create your own. An example of the questionnaire is shown in
figure 4.32.
The aim of the survey «Loyalty» is the definition of human loyalty basic principles of
security of modern society, and combating terrorism. The questionnaire includes graphics
(incentives) that increase psychophysiological effect on the test.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
120
The aim of the survey «Credit» when issuing a credit is the lack of definition lies in the
intention of the applicant for the loan and detection of fraud in obtaining credit.
The aim of the survey «Bribe» is to determine the reliability of the test person answers that
he did not take bribes at the current position.
The survey «Family» is to detect lies with whether or not he had the answer to the question
of the subject the previous evening, at work, or located elsewhere.
Questionnaire «Insider» is intended to test, to hire personnel, the possibility of selling
company secrets to competitors.
The questionnaire R_Test allows rank (to determine the significance of) the test
psychophysiological response to questions.
Questionnaire «Alco» is intended to identify those who are likely to use alcohol.
The questionnaire «Computer» is designed to identify individuals who are prone to
compulsive gambling.
Questionnaire «Violences» is intended to identify individuals who are prone to violence in
the family.
The user may develop owns questionnaires on topics of interest to him and put them in the
installation directory \ VibraImage10 \ in the same file format ld_xxxxxx.ldg.

In self-test mode, the test man is in front of the monitor, which sees the image requirements
and questions. By selecting the button «Yes» or «No» on the screen (fig. 4.34), responds to the test
questions are imposed in real time. When tested with a selection of the responses by pressing the
«Yes»/«No» as a result of the test will also be analyzed in the time delay between a stimulus
(question asked, the image) and the response (answer).
Please note, to answer this question only when the color of the question changes from black
to green. This time on the graphs corresponds to the green vertical line started lie detection. The
moment when the current question disappears from the screen corresponds the vertical line the red
color and end of the lie detection interval.
The proposed method allows to receive and to use for the automatic conclusion of psycho-
physiological information obtained 5 different independent methods during the three minute test:
1. Comparative information on psychophysiological reaction of the test (similar to the
classical polygraph) in answering the relevant (Rr) and control (Rc) questions, that
includes an evaluation of the reaction of the test at the maximum level (max result)
of vibraimage parameters:
Rc > Rr; NDI (test is passed positively if total psychophysiological reaction at
the answer to control questions is higher, than at the answer to relevant
questions);
Rc = Rr; INC (the test result isn't defined if total psychophysiological reaction at
the answer to control questions is approximately equal to reaction at the answer
to relevant questions);
Rc < Rr; DI (test is passed negatively if total psychophysiological reaction at the
answer to control questions is lower, than at the answer to relevant questions).
2. Comparative information on psycho-physiological reaction of the test (similar to the
classical polygraph) in answering the relevant (Rc) and control (Rr) questions, that
includes an evaluation of the reaction of the test at the average level (average result)
of vibraimage parameters (calculation is similar to a method 1).
3. Comparative information on psycho-physiological reaction of the test (similar to the
classical polygraph) in answering the relevant (Rc) and control (Rr) questions, that
includes an evaluation of the reaction of the test at the integrated level (integrated result)
of vibraimage parameters (calculation is similar to a method 1).
4. Information on the time delay in answering the questions. If the subject does not press
any of the buttons during the time set on this question, the system transitions to the next
question. According to the set algorithm absence of any response to the relevant
questions leads to a negative test result (calculation is similar to a method 1).
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
123
5. Information about changes in the dynamics of psycho-energetic (information-energy)
diagram of the test person at the answer to control and relevant questions. In more detail
the algorithm of calculation of this parameter is stated in the following section 5.1 of this
description.
According to set algorithm, the answer is YES to any of the relevant questions leads to a
negative test result.
The calculation of the final result of the test is carried out automatically with all the data.
The data calculation method 5 are used as the basic information. Results of the first four estimates
change the numerical value of reaction to relevant questions received by a method 5 according to
the following formula:
sRr=sR(5)r +0,1*sR(5)r*(∑NDI – ∑DI)
The final result of psychophysiological testing is defined according to the following
conditions:
NDI: sRr – sRc>0 or
NDI: sRr>0
DI: sRr– sRc<0
INC: 0,01<sRr – sRc < 0,01
4.3.8 Questionnaires stucture
According to the upgraded Bakster’s test of control questions questionnaire including three
blocks of control and relevant (test) questions (impact on the person can be strengthened by the
graphic information shown on the screen, the image of the pictures corresponding to a question) is
shown to the examinee person, general questions at the beginning and in intervals between which
are located. An example of such questionnaire indicating the time delay between the questions and
the type of questions used program is given below:

12. <GQ delay="5" length="1" text_delay="2" text_length="0" img="images/alco/12.JPG"> Thank you
for your cooperation</GQ>
To reduce the uncertainty of comparative testing must have approximately the same time
interval upon presentation of the control and relevant questions, so the length of questions and
pauses when the synchronous presentation of a variety information needs to be given increased
attention. Tag «delay» sets the interval in seconds between questions. Tag «lenght» - the time
interval of the show text of the question. Tag «text_delay» delay before the question text painted.
Tag «text_lenght» determines the speed of text painting green, if value «0» the text is painted with
a constant speed depending on the number of letters in question, at other text is painted for a
specified time.
Note the «Img» tag in the structure of the questionnaire is optional. But properly selected
image (incentives) that the respondent sees on the screen increase its psycho-emotional response to
this question (see fig. 4.35).

During the test operator notes control (by marker CQ) and relevant questions (by marker
RQ) by clicking on the corresponding toolbar button when passing these questions. After the test
the operator (the person asking the questions ) presses the button [!] on the toolbar and instantly
receives a test result in «LDr» window: True (green column - NDI), False (red column - DI) or
uncertain (yellow column - INC).
Example of comparison zones test quantitative psychophysiological responses to control and
relevant questions shown in figure 4.37.
Fig. 4.37. Lie detection process with markers.
4.3.11 Psychophysiological detection of deception in semi-automatic mode, random questions
In «LD audio mode» user needs firstly to adjust «Audio Threshold» so that background
audio level must be lower than Audio Threshold and audio level of questions and answers must be
higher than Audio Threshold. In this case every question-answer response divided by time period
not less than 10 seconds from the next question-answer response is characterized by level of
changes for every measured psychophysiological parameter. The total changes in
psychophysiological parameters are characterized by two general indicators – P5 integral parameter
indicated on the down graph, and P20 differential parameter indicated on the vertical column. More
quantity of P20 parameter after response indicates more high level of psychophysiological response
and gives more lie probability for two response comparison.

4.3.12 Recording the main test LD results
Upon completion of the survey the system will automatically go into «Pause» mode to
enable the user to analyze the results on the screen (see fig. 4.38). In the lies level window «LDr»
will display the final test result. For example, DI- the final test result is found «Lie» and the graphs
at the answer to questions 9 and 10 recorded high value P5 parameter (lie).
In «Lie level» window (LDr) on test results may be display 3 variants:
1. True (green column - NDI), then the test person has successfully passed the test.
2. False (red column - DI), it means that the test person has not passed the test.
3. Uncertainty (yellow column - INC), the test result is not clear, the test should be
repeated or modified.
Fig. 4.38. LD test results
Note, Automatically save the results to a file is only available when operating in
«questionnaires» mode.
After completing the questionnaire in lie detection mode automatically in the selected
database directory \ VibraImage10 \ Database \ *** creates files with the test results :
Data_time_histH.png – frequency histogram.
Data_time_histT.png – an analysis of changes in the human psychoemotional state at
the time of testing.
Data_time_histH.xml – system settings and change the basic parameters of the
psycho -emotional state of a person

Data_time_LD.txt – lie detector report and result files
Data_time_row.txt – full record values recorded vibraimage system parameters. This
file can be used for statistical research and testing of algorithms for determining the
psychophysical and psychoemotional human condition.
4.3.12.1 Graphics of psychophysiological state changes
Changing of psychoenergetic state of a person to a controlled period of time clearly
displayed on the graph (see fig.4.39) and in file Data_time_histT.png. Only a person who is in a
relaxed or in a state of high concentration may be in a fixed psychoenergetic state during such
insignificant time as 1 minute. Most of the people make a noticeable fluctuations of
psychoenergetic state, even for short periods of time, depending on their thoughts and under the
influence of the environment.
Color line of psychoenergetic state changes corresponds to the «color» of the test question:
general questions – blue;
control questions – green;
relevant questions – red.

Actual psychophysiological state is displayed in the form of a point and change of person’s
psychophysiological state in time is displayed in the form of a straight line or a curve between two
points. The example of psychophysiological state change from a state 0 in various states 1, 2, 3, 4, 5
is given in figure 4.40 and each transition has its emotional and psychophysiological sense.
Fig. 4.40 Psychoenergetic (information-energy) diagram of the psychophysiological state.
Transition 0-1 is characterized by an increase in energy consumption and improvement of
psychological state. The reason of this psychophysiological state change can be a good or pleasant
news (the stimulus), it leads to a more intensive exchange processes (increase in energy
consumption), and the psychological condition and mood notably improved.
Transition 0-2 is characterized by an increase in energy consumption and an even level of
psychological state. The reason can be, for example, an increase in mental and physical activity,
which lead to more intensive exchange processes (increase in energy consumption), at the same
time, the psychological state and mood are unchanged, as conducted by the impact did not cause
emotional changes.
Transition 0-3 is characterized by an increase in energy consumption and impairment of
psychological state. The reason can be unpleasant information that leads to a more intensive
exchange processes (increase in energy consumption), and the psychological condition and mood
became notably worse.
Transition 0-4 is characterized by a decrease in energy consumption and impairment of
psychological state. The reason can be unpleasant information that leads to a slowing of metabolic
processes (reducing energy consumption), and the psychological condition and mood became
notably worse.
VibraImage10 Copyright © 2017 by Elsys Corp. All rights reserved.
130
Transition 0-5 is characterized by a decrease in energy consumption and improvement of
psychological state. The reason can be pleasant news, which soothes and slows down the metabolic
processes (reducing energy consumption), and the psychological condition and mood are notably
improved.
Vibraimage technology allows to obtain multi-dimensional relationship of a
psychophysiological state characteristics and to measure not only the energy change but also the
direction of this change.
For example, The psychophysiological reactions of the person at the answer to the control
(CQ) and relative questions (RQ) are compared. In answering the question person
psychophysiological state, displayed on the diagram changes from the point with coordinates (E1,
I1) to a point with coordinates (E2, I2).
ER = E1 – E2
IR = I2 – I1
Below we consider the situation where the respondent did not like the question, he's going to
say a lie on it. Energy state in such case increases, i.e. ER < 0, and the psychological comfort is
reduced, and IR > 0.
Comparison of the sum of these indicators for answers to relevant and control questions
allows to define truthfulness of the answer or psycho-energetic expenses at reaction to the shown
answers or incentives.
R = IR + ER
If a difference Rr – Rc = dR < 0, then the person has told a lie (DI) or reacted negatively to
the shown incentive.
Hereinafter the lower indexes «r» designate value of measurement for relevant questions,
and «c» – for control questions.
The results of the human psycho-physiological reactions than the test on the 3 group of
control and relevant questions is contained in a lie detection report file in the section «IE result».

4.3.13 Ranking mode of reactions to questions
In contrast to the mode of comparative testing (comparison test zones proposed by Clive
Bakster) for many variants of psychological and psychophysiological testing necessary to obtain
information about the degree of importance of the various questions for the test person. In this case,
using a questionnaire R_Test program shows the absolute (not relative) the test reactions to
questions. In the text of the questionnaire all the questions marked with the tag <EQ>, for example:
<EQ delay=«5» length=«7» text_delay=«1» text_length=«0»> Are you often change the
decision ?</EQ>
After completing the questionnaire in lie detection mode automatically in the selected
database directory \ VibraImage10 \ Database \ *** creates files with the test results :
Data_time_histH.png – frequency histogram.
Data_time_histT.png – an analysis of changes in the human psychoemotional state at
the time of testing.
Data_time_histH.xml – system settings and change the basic parameters of the
psychoemotional state of a person.
Data_time_LD.txt – lie detector report and result files.
Data_time_row.txt – full record values recorded vibraimage system parameters. This
file can be used for statistical research and testing of algorithms for determining the
psychophysical and psychoemotional human condition.
Data_time_LD_e.txt – an additional file with the results of ranking the importance
of questions for the test.
An example of the calculation results of the file with the ranking table is shown in figure

5 Operation with external devices
The VibraImage 10 program have the ability to synchronize other devices recording
physiological parameters of the person with the VibraImage system. The synchronous registration
of different physiological processes allows expanding significantly possibilities of research of
psychophysiological and physiological characteristics of the person. Joint and synchronous
registration with the vibraimage of a pulse wave (DC21U scanner) and an electroencephalography
(Mitsar-EEG-201) allows watching visually correlation and correlation of functioning of different
physiological systems of the person.
5.1 Operation with EEG
Technology electroencephalography (EEG) is the most famous and informative for
psychophysiological testing. Therefore, it is EEG was chosen as the technology for comparative
testing vibraimage. Software VibraImage implements a joint synchronous registration and
processing of the signals of electrical activity (EEG) and motor activity (vibraimage). It should be
noted that the registered signals due to mechanical inertia of vibraimage are lower frequency than
the EEG signals, so the correct definition of the correlation between the signals should be carried
out in the frequency range up to 10 Hz.
To working EEG (for example Mitsar-EEG-10/70-201) it is not require the installation of
additional software or drivers. Enough after connecting EEG to choose an item «Mitsar-EEG».
When you connect EEG in information panels «GR» and «С» there will be additional points output
of diagrams and correlation of the following parameters:
EEG_FP1, EEG_FP2, EEG_FPZ, EEG_F3, EEG_F4, EEG_F7, EEG_F8, EEG_FZ,
EEG_Т3, EEG_Т4, EEG_Т5, EEG_Т6, EEG_С3, EEG_С4, EEG_СZ, EEG_P3, EEG_P4,
EEG_PZ, EEG_PG1, EEG_PG2, EEG_O1, EEG_O2, EEG_OZ, EEG_NZ, EEG_BIO1-
EEG_BIO8, EEG_AADIFF, EEG_EVENT.

5.2 Operation with a fingerprint scanner and registration of the pulse wave
Under development.
To use the fingerprint scanner is required initially to install the drivers. The procedure to
install drivers fingerprint scanner DC21U described in detail in the description Biofinger system
(http://www.psymaker.com/downloads/BiofingerManualEng.pdf) in the section «Fingerprint
scanner DC21U driver installation».
Note, to install the DC21U drivers, you must have administrator rights.
You can get to work after connecting a fingerprint scanner to your PC. In the VibraImage 10
program you need choose an item «DC21» in the submenu «Settings». After that there will be a
program window DCРulse (fig. 5.2). It is possible to view and process all diagrams of the program
DCPulse reflecting pulse in different points of a fingerprint figure in the VibraImage 10. When you
connect a fingerprint scanner in information panels «GR» and «С» there will be additional points
(fig. 5.1) output of graphs and correlation of the following parameters:

6 Vibraimage. General information
Values of amplitude and frequency of vibrations of a person head differ in each point of
space and are displayed as pseudo color image. Integrated processing of parameters values of
vibration in each point can give the general information on parameters of the person movement.
As against amplitude analyses, each point frequency vibraimage has physical dimension
frequencies (Hz) as really displays frequency of signal change in each element of the image.
Therefore the resulted color scale (fig. 6.1) scaling in Hz, i.e. violet color frequency vibraimage
displays a range of vibrations (0-1) Hz, dark blue displays a range of vibrations (1-4) Hz, green the
range of vibrations displays (4-8) Hz, red displays a range of vibrations (8-10) Hz (fig.6.1).
Red – activity and aggression color
Yellow – trouble and tension color
Green – normal activity and top condition color
Blue – rest and calm color
Fig. 6.1. Pseudo color scale of frequency distributions
External (around of a head) interline display of the maximal frequency and average
amplitude vibraimage looks as aura and more informatively displays a condition of the person, than
internal vibraimage. Color of vibra-aura is coded by the same color scale, as vibraimage (fig. 6.2),
and displays the maximal frequency in each line. The size of aura is defined by average amplitude
for the given line. Any non-uniformity in color and the size of aura characterizes movements of

norms.
12. Color irregularity of vibra-aura characterizes psycho-physiological imbalance of a person
status.
13. Any breaks in aura uniformity characterized deviation from mental or physiological norms.

main rules for right vibraimage scanning:
uniform and stable object illumination;
high quality and low nose camera application;
frontal plane object before camera;
maximum facial image size on monitor;
mechanical stabilization of camera.
