中值滤波在图像去噪中的应用

Computer Image Buildup Application in Getting Rid of Image Disorder

本文对中值滤波器算法进行了探讨.二维中值滤波器是一个非线性算子,按照处理窗口中像素的灰度值进行排列,然后取其中值.中值滤波器在滤除椒盐噪声方面效果很好.

The paper discusses the median filter calculation. Median filter is a un-linear operator, getting from the arrangement of gray degree value of image and then gets its median value. The median filter has good effect in filtering the noise.
