Image inpainting is a useful and powerful technique for automatically restoring or removing objects in films and damaged pictures. In the last ten years, many excellent inpainting algorithms have been proposed after Bertalmio et al.. However, no paper systematically and theoretically analyzes the factors, which limit the performances of existing algorithms. Based on extensive experiments, we firstly construct a universal framework for image inpainting, which contains three crucial factors-Area, Shape, and Perimeter (ASP). Then we propose a Pyramid model based Down-sampling Inpainting (PDI) model according to the ASP principles. Experimental results show that the performances of existing methods can be tremendously improved after incorporating the PDI model.
