FUNCTIONgetGaborKernel
RETURN TYPEMat
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Returns Gabor filter coefficients.

For more details about gabor filter equations and parameters, see: Gabor Filter.

ksize

Size of the filter returned.

sigma

Standard deviation of the gaussian envelope.

theta

Orientation of the normal to the parallel stripes of a Gabor function.

lambd

Wavelength of the sinusoidal factor.

gamma

Spatial aspect ratio.

psi

Phase offset.

ktype

Type of filter coefficients. It can be CV_32F or CV_64F .

Returns

The Mat result. Release returned native handles with using or delete(), including handles nested in results.
