Edge detection is the base of the images segmentation, image measuring, pattern recognition and so on. And it is the one of the important subjects in the field of computer vision. It is widely used in the recognition, intensification, segmentation and compress of the image, is often applied to higher-level domain. So, how to detect the edge of object quickly and exactly is a focus of image processing.
In recent decades, many scholars work around the edge detection algorithm. In these algorithm...
