图像复原技术是图像处理和计算机视觉领域共同关心的重要问题,以频谱估计运动方向以及自相关求运动尺度法的方法实现了水平运动模糊图像的增强。,我们使用MATLAB观察频谱图形的特点，估计图像的运动角度，然后用自相关的算法，求出运动尺度,最后用维纳滤波的方法恢复图像。 -Image restoration technology is an important issue in image processing and computer vision areas of common interest to the spectrum estimate motion direction and self-motion scales RELATED seek to achieve an enhanced level of motion blur of the image. We use MATLAB graphics to observe the characteristics of the spectrum, the estimated angle of movement of the image, and then use the auto-correlation algorithm obtains the motion scale, and finally with Wiener filtering method to restore the image.
