| Abstract: | In this paper,first,the traditional Canny edge detection algorithm＇s performance is analyzed and studied,the extremum inhibit process of interpolation method of direction was proposed by maintaining a Canny operator original merit in the foundation and improving gradient amplitude calculation,which not only improves the accuracy of edge detection,and restrains the pseudo edge and noise,in actual applications very good edge detection effect was made.The experimental results show that this algorithm is an effective method of edge detection improvement. |
