Abstract: The paper presents an image denoising method based on Support Vector Clustering（SVC） aiming at salt and pepper noise.The pixel point is marked as signal，the points of possible positive noise and the points of possible negative noise using local statistical characteristics.In the latter two categories，authors use iterating SVC on the gray value of pixels and deal it with noise filtering.Thus，the position of the noise will be located and the noise will be handled.Experiments show that the method presented in this paper has a very good effect on image denoising achieving 70%，especially has the better effect on the detail preserving.
