| 摘 要： | 本文系统论述超分辨率图象恢复的两大类算法,极大熵法和凸集投影法.我们用可变空间域窗法改善了GP算法,并求得最大熵法的一种情况的非线性方程组的近似解.最后给出我们的实验结果.我们还在一维情况下当收到信号的分辨率比原信号低几倍时进行极大熵恢复也得列满意的结果.

| Abstract: | This paper is to present in detail the study of image restoration by superresolution methods with the special emphasis on super-resolution methods based on the maximum entropy criterion and alternating projection of special convex sets. By successfully decreasing the window width in spatial domain, the conventional GP algorithm is improved, and at the same time the approroximate solution to the nonlinear equation system, which is derived from the maximum entropy criterion, is obtained. In 1-D case, a satisfactory restoration is also obtained with incomplete data when the sampling rate of the incoming data is lower than that of the test data by 1-5 times, Finally the experiment results are reported. |
