图象中心加权中值滤波的改进与应用

Improvement of Center Weighted Median Filters for Image

中心加权中值滤波具有较好的边缘保持特性及快速实现的特点，但滤噪能力低于其它中值滤波。此文探讨对中心加权中值滤波的改进方法，提出了中心加权分级实现的思想，使之同时具有边缘保持、快速滤波和噪声去除的理想效果。

Center weighted median filters has better characteristic on edge preservation and fast filtering,but fail in noise depression.This paper deals with a method of improvement if center weighted midian filter ,and the mutilevel center weighted filtering method is presented which makes the filters efficient in edge preservation and noise depression,and faster filtering as well.
