Abstract: Image restoration is the main research area in the domain of digital image processing. This paper introduces the Criminisi algorithm in the texture synthesis, and aiming at the problems existed in the process of making use of the priority values on the boundary to adjust inpainting order, an improved algorithm is proposed. This novel algorithm not only improves the effect of image inpainting, but also implements the replacement of big forth scenery wih digital image background. Experimental results show this improved algorithm is effective.

Key words: image restoration, image completion, texture synthesis
