一种改进的中值滤波方法

An Improved Method of Median Filtering

中值滤波是一种有效的噪声抑制技术,尤其在椒盐噪声的去除得到广泛的应用。文中针对传统中值滤波方法存在的不足加以改进,采用双阈值检测噪声,并在医学图像中进行实验,结果显示,改进后的中值滤波方法比传统中值滤波达到更优的去噪效果,图像更清晰。

The median filter is a kind of effective noise suppression technique,especially in salt pepper noise removal widely application.This paper aim at improving traditional median filtering the shortcomings of the methods,with double threshold detection noise,and in medical image experiment,the result shows that the improved median filter method than traditional median filter to achieve better denois ing effect,image is more clear.
