| 摘 要： | 提出一种新的椒盐噪声滤除方法.通过对图像二值化,对其进行统计分析确定噪声点.仅改变噪声点的像素值,避免了中道滤波对图像细节的破坏,同时又滤除了噪声.实验结果表明,新方法可以有效去除椒盐噪声,同时很好地保护图像的细节.

| Abstract: | A new filter for impulsive noise removal is presented.Median filters can remove impulsive noise but destroy the detail of images.To avoid this problem,all noise pixels must be detected first;then replaced by the median value of their neighborhood in the input image.We propose an approach based on binarization of the image,where the binary slices of an image are processed by noise-detection functions proposed in this paper.These functions can detect the polluted pixels which will be replaced by the median value.Experimental results show this method is good at removing noise and preserving the detail of images. |
