摘　　要：TV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。实验表明,在修复缺损的数字图像时,文中提出的算法与TV模型算法相比,无论是修复速度,还是修复效果,都有非常明显的提高。The TV model algorithm is a popular method of image inpainting at present,however it is time-consuming and may have bad inpainting effect.In this paper,an improved algorithm based on the TV model is given which takes the outside-in inpainting order and uses the information of undamaged or restored area for image inpainting.Besides,only one iteration is needed to finish the inpainting.The results of experiments show that the presented algorithm can achieve much better inpainting effect with much less computation time compared with the TV model algorithm.
