Description: 本文提出一种基于边缘自适应小波变换的多尺度图像修复算法，对非纹理图像有比较好的修复效
果。边缘自适应小波变换的基本思想是，先检测出图像的主要边缘，这些边缘把图像分割成几个平滑区，然后
对图像进行不跨越边缘的小波分解，即在各平滑区内部进行小波变换，得到图像的多尺度表示，并且同时计算
边缘的多尺度表示。这样的小波分解使高频信息基本都集中在边缘上，而高频系数则非常稀疏，而且都接近
于零。在此基础上进行图像修复，就只需要对低频部分与边缘图像进行修复，然后重构得到修复图像即可。
经过小波分解，低频部分破损区域大大缩小，用比较简单的插值方法就可进行修复，大大降低了计算量。对边-Abstract：A fast inpainting algorithm based on edge—adaptive wavelet transform are in—
