Robinson edge detection
WebJul 9, 2011 · Answers (1) Yes. That will work. Not sure about the Z though - you might want to take Z = sqrt (single (X).^2 + single (Y).^2) instead. Also, you might want to look into conv2 (), which I believe is more highly optimized for speed than imfilter. Be sure to use fliplr and flipud on the masks if the orientation is important though since conv2 ...
