Image inpainting algorithm based on exemplar structure characteristics

The traditional image restoration algorithm based on the sample block only considers simple structure information and will produce cumulative errors and other issues in the process of repair, which affected the overall effect of image restoration in large part, to address this problem, an improved algorithm based on Criminisi is proposed, which combines the improved priority function and new confidence item updating method. Simulation results show that the algorithm can effectively overcome the shortcomings of excessive filling in the texture-rich area and error derivative that Criminisi algorithm often appears.
