一种改进的NAS-RIF盲图像复原算法

An Improved NAS-RIF Blind Image Restoration Algorithm

摘要:

在Deepa Kundur等人提出的NAS-RIR (Nonnegativity and support constraints recursive inverse filtering)盲图像复原算法的基础上，提出改进方法。首先对非均匀背景图像进行背景校正，以扩大原算法的适应范围；接着改进求取支撑域的算法，以提高图像的复原效果；最后对求取梯度值的算法作了改进，以提高原算法的执行效率。由实验结果可看出，改进的NAS-RIF算法比原算法具有更好的图像复原性。

Abstract:

Based on NAS-RIF algorithm for blind image restoration proposed by Deepa Kundur, an improved method is proposed in this paper.In this method, background rectification is developed for non-uniform background images to expand the applied scope of the origin
