| 摘 要： | Ridgelet变换是一种新的图像多尺度几何分析（MGA）方法，它能有效地对图像进行多尺度，多方向的描述。M．N．Do提出一种可逆的，正交化的，极好重建性的Ridgelet变换实现一有限Ridgelet变换（FRIT）。本文将有限Ridgelet变换应用到线状边界明显的图像去噪中，实验结果表明，它比小波去噪取得更好的效果。

| Abstract: | Ridgelet transform is one novel method of image multiscal geometric analysis,which can suitable for describing the image in multiscal and multi-directional.M.N.Do proposed a invertible,orthogonal and achieves perfect reconstruction Ridgelet transform implement - Finite Ridgelet Transform(FRIT).In this paper,we apply FRIT to image with obvious line boundary denoising.Experiments show that it is more effective than the normal Wavlet transform. |
