Description: 反锐化掩膜技术(Unsharp Masking,UM)又称为模糊蒙片处理，是一种经典的图像边缘增强算法，提高图像的高频分量部分来增强其视觉效果[18,19].反锐化掩模技术最早是应用于摄影技术中，以增强图像的边缘和细节。光学上的操作方法是将聚焦的正片和散焦的负片在底片上进行叠加，结果是增强了正片高频成份，从而增强了轮廓，散焦的负片相当于“模糊”模板（掩模），它与锐化的作用正好相反，因此，该方法被称为反锐化掩模法。(The sharpenmembrane Technology (Unsharp Masking UM) is also called fuzzy mask processing, is a classical algorithm of image edge enhancement, to enhance the visual effect of [18,19]. unsharp masking technology was first used in photography to improve the high frequency components of the image, to enhance the image edge and details. The operation method is to focus on optical negative positives and defocus are superimposed on the film, the result is the enhancement of the high frequency component of positive, so as to enhance the contours of negative defocus equivalent to "fuzzy" template (mask), and sharpening the opposite effect, therefore, this method is called unsharp masking method.)
