Sobel            The  Sobel  filter  distinguishes
                                     between the horizontal and vertical
                                     edges  on  a  scaled  picture.  RGB-
                                     scaled pictures are generated from
                                     colour images.








                    Image Gradient   This filter finds gradient boundaries

                                     directions.












                 Generic Filters

                 Generic filters serve as a general purpose filter for those that cannot be put elsewhere.
