| Abstract: | Anisotropic diffusion equation is used to reduce digital image noise.This paper has made a theoretical analysis on the mechanism of noise reduction,presented an improve algorithm accordingly,and explained the characteristics and applicability of the algorithm.Practical experiments prove that the improved algorithm can achieve a better noise reduction.Based on the combination of the improved algorithm with median filtration,the paper claims that the blending approach can also improve the image polluted by Rayleigh noise and random dot-noise. |

| Keywords: | anisotropic diffusion image denoising Rayleigh noise edge preserving |
