摘要
被摄物与相机之间的相对运动往往会造成图像的运动模糊,给图像的识别带来不便。为了恢复这些模糊图像,文中提出了一种运动模糊图像的复原法。它利用了双线性插值及模糊方向上微分图像灰度值(绝对值)之和最小的方法来求出运动模糊的方向,其次运用传播波方程对任意方向上的匀速直线运动模糊进行恢复。将此方法应用于一个具体的实例当中,发现效果明显,由此可看出此方法是十分有效的。
<Abstrcat>An image has been blurred by relative motion between image and camera.It is unconvenient for us to recognize it.For restoration of the blurred image the paper puts forward an algorithm.First it uses the double line interposition and the minimum summation of grey value in differential coefficient image to extract the direction of motion blurred image,then uses traveling wave equation to restore the blurred image which is caused by uniform linear motion.Apply the algorithm to an idiographic example.The effect is obvious.It shows the validity of the algorithm.
