摘要
给出了Ridgelet变换的理论,并提出了一种基于尺度因子与Ridgelet变换的图像去噪算法,将Ridgelet应用于图像去噪并与小波去噪进行比较。实验结果表明,该算法对高斯白噪声污染的图像去噪具有较好的效果,不仅可以提高处理图像的信噪比,而且图像的视觉效果有明显改善。
This paper first introduces the theory of Ridgelet transform,and then proposes a method for image denoising on scale factor and Ridgelet transform. In order to indicate its advantages, it uses Ridgelet to remove noises in images,and compares the results with that of Wavelet. Experiments show that the performance of the proposed method is obviously superior to other methods both in vision and in SNR.
