【摘要】 盲图像复原是在未知或不完全确知相关原始图像与成像点扩展函数的先验知识的情形下,利用所观测到的降质图像对原始图像和点扩展函数进行估计的一种图像处理方法。本文对近年来涌现出的主要盲图像复原算法进行了回顾,并根据相应的理论来源及相互联系将其划分为四大类,对各类复原算法及其改进算法进行了分析和讨论,为更清晰与深刻地认识和理解盲图像复原理论、解决实际图像降质问题提供参考。更多还原

【Abstract】 Blind image restoration is an approach to estimate both the original image and the point spread function from degraded images,when there is no or little knowledge of the point spread function of the degraded process. In this paper,the main algorithms of blind image restoration are reviewed and classified into four types,according to their theory origins and relationships,and analysis is made for all the types of blind image restoration algorithms and relevant improved algorithms. This will be helpful to better understand the theory of blind image restoration and to restore degraded images.更多还原
