POLARIMETRIC SEGMENTATIONSupervised Wishart Classification

1: Select the Output Directory2 : Select the Output Image Number of Rows and

Columns3 : Select BMP creation files, Reject Class and

Confusion Matrix. Note: BMP and ConfusionMatrix are selected by default

4 : Enter the Window Size (Nwin = 5 ) and theReject Ratio Coefficient.(if Reject Class option isselected)

5 : Edit the ColorMap and choose the coloursassociated to the different classes

6 : Select (or not) the Coded ColorMap option7 : Enter the name of the Training Areas list text file

The default output file name is set to: Config / training_areas.txt

8 : Open Graphic Editor to define graphically theAreas of Interest (AoI) or run Text Editor to enterthe coordinates of the Areas of Interest (AoI)inthe Training Areas text file

9 : Run Training Process. This program will definethe training clusters centres from the selectedAreas of Interest (AoI).

10 : Run the Wishart Supervised Classificationprocedure


• 1 : Create a new Training Class and add it to the list. • 2 : Delete the current Training Class from the list. • 3 : Create a new Training Area and add it to the list of the current Training Class. • 4 : Delete the current Training Area from the list. • 5 : Clear the different contours on the chosen image. • 6 : Delete all the Training Classes and associated Training Areas from the list. • 7 : Save the Training Class and associated Training Areas list. • ....The default output file name is set to MD / training_areas.txt. • 8 : Rectangular selection of Area of Interest (AoI). • 9 : Polygonal selection of Area of Interest (AoI). • .... Note: The contour is automatically closed by clicking on the Mouse Right Button. • 10 : Toggle selected area contour color (black / white). • Class : Redraw all the Training Areas of the current Training Class. • Class : Move in the up/down direction in the Training Class list. • Area : Redraw the current Training Area of the current Training Class. • Area : Move in the up/down direction in the Training Area list of the current Training Class.
