Image Denoising Using Anisotropic Diffusion Equations on Reflection and illumination Components of Image

This paper proposes a new hybrid method based on Homomorphic filtering and anisotropicdiffusion equations for image denoising. In this method, the Homomorphic filtering extracts the reflectionand illumination components of a noisy image. Then a suitable image denoising method based onanisotropic diffusion is applied to each components with its special user-defined parameters .This hybridscheme donates a flexibility and customizability to the method, due to its ability to separately enhanceeach component properly. In order to evaluate the proposed method effectiveness, a number ofexperiments have been performed and the results have been compared with the results of other pioneeringmethods. The good results indicate superiority of proposed method.
