Abstract: In order to remove noise while having image fidelity, based on anisotropic diffusion model, this paper proposes the anisotropic diffusion model combined with adaptive fidelity term. The model can suppress noise on the edge and strong noise. Experimental results show that the model can effectively remove the noise, and the details and edges of the image can be a good fidelity.
