为了减小传统的反锐化掩模算法对噪声的敏感性，提出了一种新的反锐化掩模图像
增强算法，该算法在图像的平坦区域进行去噪处理，并依据人眼视觉特性对图像的不同细节
区域做不同程度的增强。通过几种算法的实验结果比较，表明本算法不仅增强效果较好，且
抑制了噪声的增强。-In order to reduce the traditional unsharp masking algorithm sensitivity to noise, a new Unsharp Masking image enha

中值滤波，去噪
实验原理：中值滤波器是将领域内像素灰度的中值代替该像素的值,对处理脉冲噪声(椒盐噪声)非常有效。为了对一幅图像上的某个点进行中值滤波处理，必须先将掩模内欲求的像素及其领域的像素值排序，确定出中值，主要功能是使拥有不同灰度的点看起来更接近于它的邻近值。-Median filtering and denoising
Test principle: median filter is to field pixel gray value instead of the pixel v
