基于Meanshift算法的图像边缘检测

n edge detection algorithm for image is proposed by referring pixel space relation and features of meanshift vector. Firstly, the meanshift vector for each pixel is calculated; secondly, regarding characteristics of meanshift theory and corresponding vector, the edge detection algorithm is implemented with the information of both length and orientation of meanshift vector. Experiment indicates that the proposed algorithm locates edge accurately and resists nose in image robustly.
