基于Contourlet变换的图像去噪算法

Image De-noising Algorithm Based on Contourlet Transform

提出了基于平移不变的Contourlet去噪方法,与平移不变小波去噪相比较,结果表明该算法能有效地消除人为的视觉效果,使去噪后的图像获得更好的视觉效果,同时PSNR也得到了很大的提高。

This paper proposes a Contourlet de-noising method based on transla tion invariance. We compare this method with the translation invariance wavelet method. The experiments show that the proposed approach can remove the visual ar tifacts, obtaining better visual result and higher PSNR.
