Returns Gabor filter coefficients

kernel = cv.getGaborKernel('OptionName',optionValue, ...)

Output

• kernel output kernel of the specified size and type.

Options

• Lambda Wavelength of the sinusoidal factor. default 10.0
• Gamma Spatial aspect ratio. default 0.75
• Psi Phase offset. default pi/2
• KType Type of filter coefficients. It can be single or double. default double.
