| 摘 要： | 本文提出了一种适合于消除图像盐椒噪声的滤波器——直方图加权均值(HWM)滤波器.该算法以加权均值滤波器为基础,利用被污染图像的直方图函数作为权值进行加权运算.实验表明,对于噪声率在5％到90％的的噪声图像,HWM滤波器具有良好而稳健的去噪效果,当噪声率超过70％时,其优越性更加突出.

| Abstract: | A new weighted mean filter,histogram weighted mean (HWM) filter,is proposed to restore images corrupted by salt pepper impulse noise.The idea is based on weighted mean filter,which uses the histogram function of the corrupted image as weight.Experimental results demonstrate that the proposed HWM filter is effective androbust for different noise ratio,ranging from 5% to 90%.When noise ratio exceeds70%,HWM filter gives superior performance compared with other known filters. |
