Abstract: In Criminisi algorithm, the confidence term is easy to tend to 0, which disorders the inpainting sequence and leads to poor inpainting effect. Besides, it also produces distortion caused by the improper matching patch which always be matched in the known area. This paper proposes a new image inpainting algorithm to solve these problems. First, a constant is introduced to make the confidence term not tend to zero, which will keep the priority formula working. Then, the point priority of obvious identified feature is increased, which is utilized to increase the priority of appropriate patch, and reduces the error matching rate. Experimental results prove that the proposed algorithm can overcome the shortcomings of Criminisi algorithm and achieves better visual effect.
