【摘要】 本文描述了一个基于小波的图像复原方法,该方法首先将图像和运算用小波表示,得到退化模型的多分辨率稀疏矩阵表示法,使用该法我们得到一个多级正则化图像复原算法,并可有效地进行平滑约束。最后,我们对所提算法进行了验证,取得了较好的结果。更多还原

【Abstract】 In this paper, we described a wavelet-based approach to image restoration. In this study, both the images and the linear operator were represented by wavelet expansions. The authors obtained a multiresolution sparse matrix representation of the image restoration. This representation induced a multigrid algorithm. The proposed approach was tested on problems of image restoration and produced satisfactory results.更多还原
