\fn CvGabor::Init(double dPhi, int iNu, double dSigma, double dF)
Initilize the.gabor
Parameters:
dPhi The orientations
iNu The scale can be from -5 to infinit
dSigma The Sigma value of gabor, Normally set to 2*PI
dF The spatial frequence , normally is sqrt(2)
Returns:
None
Initilize the.gabor with the orientation dPhi, the scale iNu, the sigma dSigma, the frequency dF, it will call the function creat_kernel(); So a gabor is created.filename The name of the image file
file_format The format of the file, e.g. GAN_PNG_FORMAT
image The image structure to be written to the file
octrlstr Format-dependent control structure
