摘要： 针对Lucy-Richardson(LR)复原算法存在的噪声放大问题，提出一种新的LR图像复原算法，通过正则化处理分离原LR算法迭代过程中的噪声残差，并采用非下采样轮廓波变换域局部邻域相关性方法对噪声进行处理，从而弥补原LR算法噪声存在的缺陷。对比实验结果表明，该算法复原视觉效果良好。

Abstract: A new Lucy-Richardson(LR) image restoration algorithm is proposed to avoid the noise amplification problem of the original LR algorithm.The problem is solved via regular method for separating the residual noise in the original LR iterative process and Nonsubsampled Contourlet Transform(NSCT) domain local neighborhood correlation denoising method. Comparative experimental results show the algorithm can obtain satisfactory restoration visual effects.

Key words: image restoration, Lucy-Richardson(LR) algorithm, Nonsubsampled Contourlet Transform(NSCT), local neighborhood correlation denoising
