edge detection techniques in image processing and computer vision occupies a special position. How to quickly and accurately extract the image edge information of objects has been a hot research at home and abroad. This article describes several classical edge detection operator and the recent emergence of a new edge detection method, and its matlab simulation studies and a comparative analysis.
