An improved image anisotropic diffusion denoise model

Diffusion has received a lot of attention and has experienced significant developments, it can simultaneously enhance, sharpen and denoise image. The anisotropic diffusion model is adjusted according to the set of image gradient, so it has many formats diffusion function. The aim of the present paper is to study function´s character and propose a new diffusion function according to the Aubert model. The results of experiments demonstrate the novel diffusion model denoise the image and retain the details more effective than Aubert diffusion model.
