gabormask.rar
Gabor-function convolution masks are increasingly used in image processing and computer vision. This function simply computes the cosine and sine masks for a given width, period and orientation. The masks returned are properly normalised.
It is not ...

myfft_ifft.zip
FFT and IFFT for 16-bits wave, you can
use this instead of convolution calculate, input samples must be 2^n.
If its not 2^n samples just stuff zero
in last array.
I already make it to C++ class you can
new a calss and do it easy

conv_fft_ifft.zip
include FFT IFFT and using FFT to calculate convolution and round off.
Its useful for wave 16 bits.
