中文说明：
针对传统的基于小波变换的反锐化掩模图像增强算法中存在的问题，即对比度相同而幅角不同的边缘达到的增强效果之间差别较大，提出了一种新的基于小波变换的反锐化掩模图像增强算法。该算法在对原始图像进行小波分解的基础上，根据小波变换所提供的幅角，对小波系数进行。
English Description：
In view of the problems existing in the traditional anti sharpening mask image enhancement algorithm based on wavelet transform, that is, the enhancement effects of edges with the same contrast and different angles are quite different, a new anti sharpening mask image enhancement algorithm based on wavelet transform is proposed. Based on the wavelet decomposition of the original image, the wavelet coefficients are decomposed according to the amplitude provided by the wavelet transform
