In the image inpainting process

the Criminisi algorithm easily confuses texture parts for edge parts

resulting in inpainting sequence deviation which finally influences the inpaint effect. By making full use of the characteristics of image textures and edges

we introduce a differential-factor to improve the ability of the algorithm to distinguish edge parts. At the same time

the improved algorithm uses a new search method to prevent the appearance of flaws during the image inpainting process. Experiments confirm that the improved algorithm can overcome the insufficiencies of the original algorithm such as texture extension and can better maintain linear structures. The Power Signal-to-Noise Ratio of the result compared to the original algorithm has been improved about 2 dB to 3 dB

and the results have a better visual appearance.
