该算法主要用来计算PSNR值，能够求出生成图像与原始图像的客观对比-Image inpainting refers to reconstructing the corrupt regions where the data are

l destroyed.A primary class of the technique is to build up a partial differentia

uation,consider it as a boundary problem,and solve it by some iterative method

he most respresentative and creative one of the inpainting algorithms is BSCB

odel.After summarizes the development of image inpainting technique,this pape

oints the research at the improvement on BSCB model,and proposes three

gorithms to solve the two drawbacks of this model.The first is selective adaptive
