| Abstract: | Ridgelet transform and finite ridgelet transform are introduced in this paper.And shift-invariant denoising using finite ridgelet transform is proposed in this article.Experiment results show that the new algorithm is more effective than other algorithms in smoothing gaussian noise.At the same time the new algorithm is good at preserving detail of image. |
