基于小波变换的分层影象恢复

Wavelet Based Hierarchical Image Restoration

此文研究了影象恢复问题的小波表示，提出了基于小波变换的分层影象恢复算法。该方法不仅可以改善影象恢复的质量，而且其计算量远远小于通常的影象恢复算法。

s The wavelet based representation for the problem of image restoration is investigated and the algorithm of hierarchical image restoration based on wavelet transform is presented. This method can not only greatly reduces the time consumption for image restoration, but also improves the qualities of result images.
