Robinson
The Robinson Edge filter is use to detect edges using a horizontal and verticle kernal filter. Both filters are applied to the image and summed to form the final result. The two filters are basic convolution filters of the form:
+2 +3 +2 +2 0 -2 0 -2 +3 +3 -2 0 0 0 0 +3 0 -3 +2 0 -2 -2 0 +2 -2 -3 -2 +2 0 -2 -3 +2 0 0 +2 -3
