The Canny Edge Detector - AI Shack

WebThe first step in Edge Detection algorithms is to determine the intensity of an RGB tuple.Intensity is a measure of a pixel’s saturation. Which is more intense, a pixel which is full red (255, 0, 0) or a pixel which is full green (0, 255, 0)?Trick question (we hate those too)! They are the same intensity!. We need a way to map from RGB tuples to a single … WebThe filter searches for objects' edges by applying Canny edge detector. The implementation follows Bill Green's Canny edge detection tutorial.
