一种基于模糊人物图像的锐化新方法

本文提出了一种基于模糊人物图像的锐化新方法。该方法是先从彩色图像中提取R分量图像进行边缘检测并且照亮边缘,然后处理边缘图像的对比度和平滑度,提取出边缘,并对该边缘图像进行锐化,得到了图像边缘锐化而其它部分平滑的清晰图像。该方法和常用的反锐化掩模法进行了对比,效果明显好于反锐化掩模法。

A New Method of Sharpening Blurred Figure Images

This article is about a new method of blurred figure image sharpening.Its steps are as follows: First,extract the R-image from a color image,detect its edge and lighten it.Second,adjust the contrast degree and the blur degree of the edge image,extract the edge and sharpen the edge of the original image,and then a clear image with its edge sharpened and other parts smoothed can be obtained.This method is better than the commonly-used method of unsharpening mask.
