数字影象复原的状态空间方法

本文阐述了数字影象复原的一种空间域递归处理方法——状态空间方法,并把这种方法从复原运动模糊影象推广到复原一般的二维退化影象。文中推导了退化系统模型的状态空间表示式,在无噪声的情况下,导出了一个逆系统模型以复原模糊影象。基于逆系统模型,本文还推出了一个复原运动模糊影象的新的简单公式。文中给出了计算机模拟实验的结果。

State Space Method of Digital Image Restoration

A recursive processing method in space domain,state space method,used in digital image restoration is described.The use of this method has been further extended from restoring motion blurred images to recovering general 2-D degraded images.The state space presentation of degraded system models is firstly developed.In the noise-free case,an inverse system model used to solve the restoration problem of degraded images is then derived.Based on the inverse system model,a new simpler formula used to recover the image blurred by motion in one direction is also given.The results of computer simulation experiments are presented.
