An algorithm for image restoration based on tight wavelet frames

摘要：

In this paper, a soft threshold de-noising algorithm that different wavelet decomposition layers use different tight framelets is proposed to the restoration of degradation images. As the example, Bspline of 2-order and 4-order are taken to analyze the image; Moreover, the numerical experiments show that the algorithm in this paper is better than that with the same framelets in different layers for restoring degradation image.
