运动模糊图像的光流场分析

由于运动模糊图像含有运行信息，提出了采用光流场分析的方法对其运动结构进行分析。整个过程分为两部分。首先，根据恢复图像恢复理论估计出点扩展函数，并对盲运动模糊图像进行恢复。然后，根据运行模糊图像的运动信息得出运动位移，然后进行光流场分析。

Motion Analysis to Motion-blurred Image Based on Optical Flow

The image taken is blurred because of the relative motion between camera and object. But on the other hand, there is information of motion structure in blur motion image. So it can be used to infer the velocity locally of the object. On the base of this, we try to restore the motion-blurred image, then simulate the motion frames of the object according to the magnitude and the direction of the scene being blurred. Thus, the optical flow of image can be computed from the restored image and the object's velocity. Meanwhile, the exposure time when the image was taken is short, the difference between the frame is so tiny that the simulated motion frames are fitted for the assumption of the optical flow computation.
