Performance Analysis and Comparison of SUSAN Edge Detector

SUSAN edge detector based on gray comparison is introduced in this paper.How to choose the template and threshold is discussed too.SUSAN edge detector to image is realized using VC++.By comparison with traditional edge detection method,the experiment results and analysis show that because this algorithm don't deal with grads operation,so the effect of SUSAN edge detector to image containing noise is excellent than traditional edge detection method.SUSAN edge detector is suit to image containing noise and gray image of low contrast.
