| 摘 要： | 本文论述了统计复原的各种最佳准则,这些准则曾广泛地应用于线性或非线性图象复原方法中;指出了最大信息法(MI)更适合复原天文图象。在图象复原领域内,引入了三种新的图象复原准则—最大图象信息法(MII)、最小视觉约方差法(MPMSE)和最小检测概率均方差法(MDP—MSE),前者基于模糊集原理,后两者基于人眼视觉特性。着重讨论了基于检测概率的复原准则(MDP—MSE)、最大信息复原准则(MI)。

| Abstract: | Various kinds of optimal criteria for the image restoration are investigated statistically which have been widely used in both linear and nonlinear restoration methods.It is pointed out that the Maximum Information(MI)criterion works well for restoring astronomical images,and three new criteria in the domain of image restoration are introduced which are respectively the Maximum Image Information(MII),Minimum Perceptual Mean Square Error(MPMSE)and Minimum Detection Probability MSE(MDP-MSE).Among them the former is based on the principle of Fuzzy sets and the later two are based on the visual system models.The criteria of MDP-MES and MI are emphatically discussed. |
