public class EdgeDetect
extends RGBAllFilter
Edge-detection filter.

Outlines the edges of an image. The edge detection technique used is to take the Pythagorean sum of two Sobel gradient operators at 90 degrees to each other, separately for each color component. For more details see "Digital Image Processing" by Gonzalez and Wintz, chapter 7.

This filter is slow.
