Abstract：Based on the analysis of local characteristic of nature images

a fast and non-iterative inpainting algorithm using adaptive mask is proposed in this paper. First

the direction of isophotes is estimated through sorting. Accordingly

the restore mask can be chosen adaptively. Then

the whole damaged area can be restored along the routine which defined by the fast marching method. The experimental results show that this algorithm has better ability in restoring both smooth area and edge-contained area compared to other fast inpainting algorithms.
