Research of Diffusion Coefficient in The Total Variation Image Inpainting Model

In this paper, structural conditions of diffusion coefficient are presented according to the theoretic analysis about the total variation image inpainting model. Theoretic analysis shows that the diffusion coefficient, which satisfies with the structural conditions, has favorable capabilities. Then, according to the structural conditions, a new diffusion coefficient and its corresponding inpainting model are presented. Experimental results indicate that, compared with the TV algorithm, the new algorithm has better performance in the quality of inpainting and needs less computing time.
