Denoising is a crucial step to increase image conspicuity and to improve the performances of all the processing needed for quantitative image analysis. In this paper, the main method we proposed is Non Local Means. We carried out our experiments based on 3D MR images from Brain Web. We compared The NL-means with some classical methods, such as Anisotropic Diffusion Filter and Bilateral Filter. The results show that the Filtering performance of NLmeans is better than other methods. Moreover, we
