| Abstract: | A PDE-based Perona-Malik model was introduced in this paper. Combined with the idea first presental by Catteabout Gaussian diffesion filter, a method for MRI image denoising was presented with its realization. According to differentparameters given, results were compared and analyzed. The method was applied to medical images and its results wereencouraging. |
