to extract features. 32 Gabor kernel function corresponding to 32 times transform can extract 64 characteristics (including mean and variance). Because the whole transformation process code is complicated, only provide test code for download here. This code can only calculate a 101 x 101 size of the Gabor function transform, get the mean and variance. Code USES two kinds of convolution calculation, can be seen the results, the efficiency of the fast Fourier transform (convolution is discrete two-dimensional superposition and nearly 50 times of convolution.
