V模型算法是目前较为流行的图像修复算法，但其修复速度慢，修复效果不是太理想。文章对TV模型进行改进，采用从外到内的修复顺序，并完全采用已知区域信息对图像进行修复，所有待修复的点仅需1次迭代便可完成修复-The V-model algorithm for image restoration algorithm is currently more popular, but its slow repair, the repair effect is not too satisfactory. Article to improve the TV model, the use of a repair order from outside to inside, and fully known regional information to repair the image, all point to be repaired only one iterations to complete the repair
