摘　　要：介绍超分辨率图像恢复的概念、起源、应用和先决条件,以及超分辨率图像恢复包含的图像处理步骤和计算上需要有效处理的两个问题;综述国内外超分辨率图像恢复研究现状,对超分辨率图像恢复的主要方法及空域方法中的主要类别进行评述,并介绍超分辨率图像恢复算法的评价方法;最后对超分辨率图像恢复的研究前景进行展望。Super resolution image restoration（SR）is a new image processing branch, which restores one bettex image of higher resolu-tion from a degraded image sequence of lower resolution.Algorithms of SR can be used wherever image resolution is not contented and image sequence can be obtained.The concept,craning into beings, applied fields and preconditions of SR are introduced.The involvedimage processes and two actual computation questions of SR are described.Research status of SR at home and abroad are summarized,main types of SR methods,maln sub- types of spatial SR are evaluated,and the evaluation method of SR is introduced.And at last,anattempt is made to give some foreground expectations of SR.
