Abstract

Abstract: This paper propses a Ridgelet de-noising method based on translation invariance.We compare this method with the translation invariance wavelet method.The experience show that the proposed approach can remove the visual artifacts，obtaining better visual result and higher PSNR.

Key words: Ridgelet transform, fast slant stack, radon transform, transform invariance

摘要： 提出了基于平移不变的ridgelet去噪方法，与平移不变小波去噪相比较，试验结果表明平移不变的ridgelet算法在消除和抑制噪声的同时能更好地保留图像边缘特征，并且显著改善了峰值信噪比。

关键词: Ridgelet变换, 快速slant stack, radon变换, 平移不变
