本文讨论了H/SUB/SPL INFIN//反卷积滤波器的设计及其在图像恢复中的应用。提出的H/SUB/SPL INFIN//去卷积滤波器在处理未知边界问题和空间变化的模糊方面具有一定的优势。本文将H/SUB/SPL INFIN//滤波器与逆Wiener滤波器和正则化恢复方法进行了比较。实验结果表明，H/SUB/SPL/INFIN//滤波器比维纳滤波器更好地处理未知边界问题。与正则化方法相比，该方法可以得到更清晰的恢复图像，特别是当原始图像包含较多细节时。
This paper addresses the design of an H/sub /spl infin// deconvolution filter and its application to image restoration. The proposed H/sub /spl infin// deconvolution filter has some advantages for image restoration in its capability of handling unknown boundary problems and spatially varying blurs. In this paper, the H/sub /spl infin// filter is compared with the inverse Wiener filter and a regularized restoration method. The experimental results show that the H/sub /spl infin// filter deals with the unknown boundary problem better than the Wiener filter. Compared with the regularization method, it gives a sharper restored image, especially, when the original image contains many details.
