| 摘 要： | 提出了一种改进的运动模糊复原算法,首先利用改进的高通滤波(方向微分)快速算法判定运动模糊方向,然后利用边缘检测算法计算模糊尺度,从而确定点扩散函数,最后通过维纳滤波算法对模糊图像进行恢复。针对K值估计问题,提出了一种新的K值自动估计算法。实验结果表明,该方法鲁棒性强、实时性好,图像复原效果好。

| Abstract: | This paper presented an improved motion blur restoration algorithm.First of all,the improved high-pass filter(the direction of derivative) fast algorithm was used to determine the direction of motion blur,and then used the edge detection algorithm to calculate fuzzy scale,so that the PSF was determined.Finally,the Wiener filter algorithm was used to recovery the fuzzy image and a new algorithm was proposed to solve the problem of inaccurate estimated K values.This method has better robustness,faster process... |
