hi, i want to find the auto correlation & cross correlation in horizontal ,vertical & in diagonal direction of the output image obtain after doing the quantization of image*(*this image is obtain after taking the FFT of image & then finding the magnitude of that image)in to four level(quantization is done by dividing the minimum to maximum range in to four level and replacing each level with 1,2,3& 4 respectively) the output image who's auto correlation is to be find.consist of image array of size 256×384 having the values ranging from 1 to 4 only please help me to find it because i don't have any idea how to find it
