摘　　要：通常图像恢复方法均在成像系统的点扩展函数PSF已知下进行,实际上它通常是未知的。在PSF未知的情况下,盲解卷积是实现图像恢复的有效方法。该算法优点是,在对失真情况毫无先验知识的情况下,仍能实现对模糊图像的恢复操作。给出了利用MATLAB实现的图像恢复实例,并对恢复图像的失真情况做了改善。In a general way, the restoration of images is processed with the fact that the PSF of imaging system is ageneral.Actually it is unknown commonly.In such condition ,blind deconvolution is the effective method to realize images restoration.This paper discusses the method for blurring images restoration.The blurring factor is not necessary to be known in advanced to restore these images.At the last of the paper,there is the example of image restoration based MATLAB ,and improving about distortion of the images after restoration.
