  • Traditional speckle removal methods generally result in the lost of image features. This paper presents a new approach to edge-preserving smoothing of digital SAR images based on the PDE's. A brief analysis of the principle of anisotropic nonlinear diffusion equation for image restoration is introduced, and then an edge indicator is showed in the final update equation to constrain the image edge, staying as close as possible to the input image and to restore discontinuities, which improve the ability of speckle noise removal. Comparison and experimental result show the new proposed algorithm has high performance.
