Abstract: A novel image inpainting method based on improved Criminisi algorithm to solve the defects of Criminisi algorithm which hardly yields unfavorable results and costs much inpainting time is proposed. The priority levels of the blocks are obtained and the optimal inpainted block is selected, and then the optimum matching block in the image is found by improving search method, and the confidence value is updated to obtain good inpainting results. The simulation experiments are carried out to test the performance. The experimental results show that compared with Criminisi algorithm, the proposed algorithm is effective in both guaranteeing the quality of repaired images and saving much more repairing time.
