WebNotice that the result has negative values. To avoid negative values in the output image, convert the input image to uint8 before performing the filtering. Since the input to imfilter is of class uint8, the output also is of class uint8, and imfilter truncates negative values to 0. A = uint8 (magic (5)); imfilter (A,h)
