摘要
在运动模糊图像恢复中,常用的方法都是基于滤波算法,这些方法计算比较复杂。针对图像模糊参数未知情况,对其频谱图采用Radon变换,然后分别基于MRT和IPM方法得到模糊方向和模糊尺度,最后采用基于Z变换的离散递推算法恢复出图像,得到了质量较高的恢复图像。
In restoration of motion blurred image,the methods commonly used are based on filtering algorithm,but those methods are rather complicated.In this paper,as the blur parameters is unknown,we take Radon transform for motion blurred image＇s spectrum,and then we get fuzzy direction and scale which are based on the MRT and IPM methods.Finally,we use discrete recursive algorithm which based on Z transform to restore the blurred image.The satisfying results are gained by means of computer simulation.
