Image Denoising Using Anisotropic Diffusion Equations on Reflection and Illumination Components of Image
International Journal of Engineering · 2014
This paper proposes a new hybrid method based on Homomorphic filtering and anisotropic diffusion equations for image denoising. In this method, the Homomorphic filtering extracts the reflection and illumination components of a noisy image. Then a suitable image denoising method based on anisotropic diffusion is applied to each components with its special user-defined parameter. This hybrid scheme donates a flexibility and customizability to the method, due to its ability in properly enhancing images components. In order to evaluate the proposed method effectiveness, a number of experiments have been performed and the results have been compared with the results of other pioneering methods. The good results indicate superiority of the proposed method. doi: 10.5829/idosi.ije.2014.27.09c.03
