WebAbstract: Canny Edge Detector is the most widely used operator for edge detection. The problem with Canny is that it outputs a binary edge map, where an edge pixel (edgel) is marked (e.g., its value in the edge map is 255) and a non-edge pixel is unmarked (e.g., its value in the edge map is 0). WebThe binary edge image in Fig. 4 was obtained by edge detecting the image in Fig. 1 using the Canny algorithm. By using an edge map we could extract horizontal and vertical borders of each...
