Image inpainting based on wavelet transformation

During the time of manual image repair, people tend to follow the principle of the first repair after the overall structure repair of texture details. In this paper, taking into account that the partial differential equation model has strong capacity of keeping linear structure, and texture synthesis model has good effect in repairing the texture information, the defect image is decomposed into structural image and texture image by wavelet transformation, and then the structural image is repaired by partial differential equation model; the texture image is repaired by texture synthesis technique. The experimental results show that the algorithm can effectively improve the quality of image inpainting.
