Abstract: For the image inpainting algorithm based on examplar，proposed by Criminisi and his partner，has some deficiencies in determining matching block size，this paper presents an improved algorithm.To obtain a more accurate match，this algorithm determines the matching block size according to the size of texel sample，and uses multi-level synthesis method to improve the repair result，it makes up the deficiency of structural fracture during Criminisi algorithm.The experiment results show this method is effective in repair structured texture images.
