The research of Tibet mural digital images inpainting using CDD model

The paper introduce the repair technology of one of the main algorithm - CDD algorithm, analysis of the breakage of the digital image types and corresponding repair methods, under the condition of the damaged area is larger, in this paper we extend the classical CDD model with another TV model contrasted the performance of repair, The results show that the former both on the edge of the connection integrity and consistency are better than that of the latter. under the premise of guarantee the quality of repair, the model can greatly improve repair efficiency.
