| 摘 要： | 在对现存的图像盲解卷积恢复算法进行阐述的基础上,介绍了一种根据概率统计理论推导的极大似然图像恢复算法.该算法通过用共轭梯度法对一个误差函数进行最小化来实现.并且在运算的过程中,加入了一些先验知识,如非负性和有限支持域等约束. |
| 关 键 词： | 图像恢复 先验知识 误差函数 盲解卷积 |

| Abstract: | On the basis of introducing the existent blind deconvolution image recovery algorithm, a maximum likelihood image recovery algorithm deduced from probability statistical is presented in this paper, This algorithm is implemented through minimum a error function using the conjugate gradient method. And during the calculate process, some prior knowledge such as non-negative and limit support is incorporated. |
| Keywords: | image recovery prior knowledge error function blind deconvolution |
