In order to preserve edge while removing noise,an anisotropic diffusion median filter is proposed for low-signal-to-noise image.The method includes two steps: firstly,to achieve much better noise suppression with robust capability of edge-preserving,anisotropic diffusion is employed to image processing,whose diffusivity function is Tukey function;secondly,in order to remove impulse noise,median filter is employed for the processed image.So this algorithm can achieve much better noise suppression with minimum edge blurring.The experimental result shows that our has good capability in noise suppression and edge-preserving.
