空域中退化图像恢复的有效算法

AN EFFECTIVE RESTORATION ALGORITHM OF DEGENERATED IMAGE IN SPATIAL DOMAIN

在作者先行研究工作——频域正则化参数自适应修正模式的基础上，对退化图像的空域正则化恢复提出了隐式迭代算法及改进的近似求逆技术，并对隐式迭代过程中解的稳定性与逼近性给予了分析．试验表明，在迄今的所有退化图像空域恢复技术中，该算法是十分成功的，它的高质量恢复图像与合理的机时开销。

An implicit iteration algorithm and an improved approximately inverse matrix technology used in image restoration in spatial domain are put forward in this paper based on author's prior work of adaptive correction of regularization parameter in DFT domain. The stability and approximate of solution are analyzed in implicit iteration. The experiment results show that the algorithm is a success on high quality image restoration and suitable time consumption.
