In order to recover the missing information after removing small objects from an image,such as the scratches and characters,we analyze the total variation(TV) model and its self-adaptive algorithm in this paper.Based on the image inpainting principles proposed by Tony F.Chan,the weight coefficient in the original algorithm is improved with two proposed threshold parameters.Simulation results show that the proposed algorithm can improve the computing speed effectively,and at the same time,can keep the simila...
