摘要
Abstract
TV image inpainting only repairs algorithm along the vertical direction,making diffusion gradient in smooth area into stair step effect,reducing iterative efficiency,producing false edge faults. We analyse and compare the TV image restoration model and repair the performance of the model is put forward in this paper. Puts forward an improved image restoration algorithm,the algorithm in combination with the isotropic and anisotropic diffusion,the use of regional frequency difference in different area realized the use of different iterative equations,effectively avoid the original algorithm introduces ladder effect,to improve the iterative efficiency. The experimental results show that the algorithm and the TV algorithm, have the same effect on the premise of repair,the algorithm avoids the stair step effect at the same time with the model is better than TV repair speed.关键词
