对图像消噪的中值滤波器的改进

Improving Middle-filter of Erasing Image′s Noise

阐述了中值滤波器的原理 ,分析了中值滤波器的缺陷 ,即不适合对内容复杂、细节较多的图像进行消噪处理。本文针对这个缺陷对传统中值滤波器进行了改进。最后 ,给出了传统的中值滤波器和改进后的中值滤波器对图像消噪的结果 。

In the paper, the principle of the middlefilter was described and analyzed disadvantage of middlefilter. It drew a conclusion that it was not suitable to erase complex images′ noise. It needs to improve middlefilter. The paper improved traditional middlefilter according to the character of actual images. Lastly, the paper compared the improved middlefilter with the traditional middlefilter and discussed the merit of it.
