自适应加权中值滤波图像去噪算法

Adaptive Weighted Median Fiter For Image Denoising

中值滤波是常用的降噪算法,本文提出了一种基于窗口拟合曲线的斜率信息的自适应加权算法。该算法具有较好的边缘保持特性及去噪性能。

Median filter is a common denoising algorithm. This paper proposes a new adaptive weighted algorithm based on the slope of the curved liner. Experimental result shows that this algorithm has better characteristic on edge preservation and depression of the noise.
