• correl(correlogram, F, G) -> It implements correlation sequence: here one transfers imgs f and g from correlogram buffer to F and G, then one performes FFT in place. Then, convolution product is done in correlogram buffer. Finally ifft and shift methods are applied. The correlogram is Correlogram[0] = real(ifft(F.G*)) while Correlogram[1] = im(ifft(F.G*)).
