摘要 该文对Ridgelet变换以及FRIT(FiniteRidgeletTransform)变换作了介绍,并在此基础上提出了基于FRIT变换的平移不变去噪算法。实验证明该算法能有效地去除图像的高斯噪声,同时能很好地保留图像的细节信息。 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.
