摘　　要：SUSAN算法是一种基于图像灰度比较的算法,不涉及梯度的计算。对基于灰度比较的SUSAN边缘检测算法进行了讨论,提出一种改进的SUSAN边缘检测的算法。首先对边缘做初步的估计,然后再运用SUSAN算法对边缘定位。最后对该算法用VC++进行了编程实验,实验证明改进后的SUSAN算法在计算量大为减少的情况下,边缘检测效果不会变差。SUSAN edge- detecting algorithm is based on comparing between gray of pixels. It doesnr s need computer grads. This article introduces SUSAN algorithm,and an improved SUSAN edge- detecting algorithm is proposed. At first the primary edge should be estimated, then applies SUSAN algorithm to orientate edge. At last SUSAN algorithm is programmed by VC＋＋. Although the account is decreasing, but the experimental results indicate that the performance of improved SUSAN algorithm is as good as the primary algorithm.
