【摘要】 引入了色度比的概念,提出了利用色度比进行图像噪声和边缘检测的算法,设计了一种基于色度比的新型滤波器。实验结果表明,该滤波器可以有效地去除图像中的噪声,并能较好地保持图像的边缘细节信息。更多还原

【Abstract】 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.更多还原
