Images Similarity Engine.Vayar Vision

Similarity Engine

Similarity Engine : Finding images similar to some given image in

some image database.1) First step: basic features definition2) Indexing of all images in database by help

these features3) Indexing of some given images by help these

features4) Finding image (or images) with maximum

feature similarity from database

large number of investigation exists in the field of images similarity. But the current Engine:

1) Can generate almost infinity number of features used for images similarity.

2) The system can learned from mistakes.3) The system can be easily adaptive to some new

definition of similarity4) The set of used feature has no semantic sense.We don’t make recognition of objects on image

and use such no sense features as number of pixels on object boundaries and etc.

Found similar images by help our Engine from terragaleria site

Field of use

1) Images similarity engine in Internet (like Google for words)

2) Finding relevant images in film for product advertising setting

3) Finding relevant information about some building or place from photo or film.

4) Navigation by place recognition from photo or film (GPS equivalent) by help Google Earth

5) Find similar images for intellectual property rights control

Recovering Epipolar Geometry from Images of Smooth Surfaces

Technion

We present four methods for recovering the epipolar geometry from images of smooth surfaces. Existing methods for recovering epipolar geometry use corresponding feature points that cannot be found in such images. The first method is based on finding corresponding characteristic points created by illumination (ICPM - illumination characteristic points method). The second method is based on correspondent tangency points created by tangents from epipoles to outline of smooth bodies (OTPM - outline tangent points method). These two methods are exact and give correct results for real images, because positions of the corresponding illumination characteristic points and corresponding outline are known with small errors. But the second method is limited either to special type of scenes or to restricted camera motion. We also consider two else methods, termed CCPM (curve characteristic points method) and CTPM (curve tangent points method), for search epipolar geometry for images of smooth bodies based on a set of level curves with a constant illumination intensity. The CCPM method is based on search correspondent points on isophoto curves with the help of correlation of curvatures between these lines. The CTPM method is based on property of the tangential to isophoto curve epipolarline to map into the tangential to correspondent isophoto curves epipolar line. Unfortunately these two methods give us only finite subset of solution, which usually include "good" solution, but don't allow us to find this "good" solution among this subset. Exception is the case of epipoles in infinity. The main reason for such result is inexactness of constant brightness assumption for smooth bodies. But outline and illumination characteristic points are not influenced this inexactness. So the first pair of methods gives exact result.

SONOS Transistor

Flash memory designTower Semiconductor LTD

• Silicon–oxide-nitride–oxide–silicon memory transistor, where information is stored as two charges in nitride at the edges of the channel.

• Silicon-Oxide-Nitride-Oxide-Silicon memmory (SONOS) • A SONOS memory cell is formed from a standard polysilicon NMOS

transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thick oxide lower layer, a 5 nm thick silicon nitride middle layer, and a 5—10 nm oxide upper layer.SONOS promises lower programming voltages and higher program/erase cycle endurance than polysilicon-based flash. SONOS distinguished from mainstream flash by the use of silicon nitride (Si3N4) instead of polysilicon for the charge storage material.
