一种保边缘的图像去噪方法
Edge-preserving Image Denoising Method
摘要
Abstract
This paper proposes a edge-preserving image denoising method. The noise point and noise-free point are computed by four directional convolutions operators, and noise-free point are not dealed with. The mininum distance noise-free point in the 3×3 neighborhood is obtained. If there is not noise-free point, the neighborhood is extended to 5×5. The median value of them is used to replace the noise point while existing noise-free point. Otherwise, the noise point is replaced by the average value of the maximum distance pixel. Experimental result shows that the algorithm can effectively remove image noise, and can better protect the image edge.关键词
