：：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-:: For the traditional wavelet transform based on unsharp masking image enhancement algorithm for the problems that exist, that is, the same contrast ratio and increase the edge angle to achieve different effects to enhance the difference between the larger, a new wavelet-based unsharp masking of image enhancement algorithm. The algorithm in the original image based on wavelet decomposition, wavelet transform in accordance with the increase provided by angle of the wavelet coefficients
