Design of a New Filter Based on Image'''' s Chrominance Ratio
一种基于图像色度比的新型滤波器的设计

Chrominance ratio is introduced and an algorithm checking noise pixels and the edge of image based on chrominance ratio is presented and a new filter based on image's chrominance ratio is designed. Experimental results show that the filter can preserve the edge and detail of image very well when removing noise in effect.
