一种新型的混合滤波器的设计与实现

Design and Realization of a New Mix Filter

对空间域的常用噪声滤波技术的不足进行了分析,提出了一种线性与非线性混合滤波算法。该算法充分结合了中值滤波器和均值滤波器的优点,比均值滤波器和中值滤波器具有更好的抑制噪声的能力,能较好地保持图像的边缘和几何结构细节。最后给出了几种滤波技术的滤波效果比较图,验证了文中提出的滤波新方法对椒盐噪声和高斯噪声的滤除能力。

Analyses the disadvantage of the normal noise filter technique in spatial domain and poses a mixed linear and non-linear filter algorithm. The algorithm completely combines the advantages of average filter and median filter, but has a better capability of suppressing noise than them and can better preserve the margin and the details of geometric pattern of image. Finally several compared diagrams of the filtering effects of this technique are demonstrated, proving the filtering ability of the new technology posed in the article to salt noise and Gauss noise.
