Description

It computes a one pixel of the image or matrix, including, possibly, averaging over neignboring pixels, and the standard deviation of the neighborhood.

Syntax

int MakePixelProfile( int row, int col, OImageMakePixelProfileParams * pstParams, vector & vectOut, vector & vectOutAux = NULL )

Parameters

row: [input] the ros index of the pixel
col: [input] the column index of the pixel
pstParams: [input] additional information about how the profile determination ought to proceed:; OImageMakePixelProfileParams::radius = the size of the radius around the pixel for averaging, etc. If 0, only the value at the pixel is returned.
vectOut: [output] the value for each frame at the pixel.
vectOutAux: [output] the standard deviation for each frame at the pixel.

Return

0 if success, otherwise FALSE.
