An edge detection method is based on FCM clustering and Canny operator for remote sensing image is proposed.In the algorithm,median filter is first used to eliminate non-Gaussian noise of original remote sensing image; then,FCM (Fuzzy C-mean) is used to divide pixels of image processed into two categories:edge pixels and non-edge pixels,and clustering image can be obtained; finally,Canny algorithm is used for clustering image to get ground objects edge information of remote sensing image by edge detection.The experiment results show that the proposed method can denoise effectively and accurately the edge of ground objects.Proposed method is an effective edge detection method for remote sensing.
