I don't understand your question. But you might start with imgradient() or imgradientxy().

for image 256*256 calculated edge pixel and corresponding gradient direction such as 0,45,-45,-90 now for every edge pixel i need to calculate pixel difference based upon their corresponding direction and if the difference satisfy threshold value then need to store those pixel values. Please help in this regard
