This paper proposes a novel image inpainting algorithm based on exemplar repaired in a sequential manner. This method makes a new experiment on inpainting order of Criminisi classical algorithm. The inpainting order of the classical algorithm is obtained by calculating the priority. But the priority is tending to 0 with the sustained inpainting. As a result, the algorithm will fail and produce error inpainting results. In order to solve this problem, we replace the priority determined order with a sequential manner, which can keep the algorithm working all the time. Moreover, we propose a novel exemplar pattern like an inverted L. The pattern in our method can help to enhance the ability of structure propagation and improve correction rate of patch matching. Experimental results prove that the novel algorithm can achieve better visual effects.
