基于空间域的车辆运动模糊图像的恢复
Restoration of vehicle motion-blurred image based on spatial domain
【摘要】 从车辆运动模糊图像产生的机理出发,分析了运动模糊图像的退化模型,给出了一种在空间域中车辆运动模糊图像的运动参数估计及恢复算法,该算法不涉及系统的传递函数,而是根据车辆运动模糊的逆过程在空间域内直接进行图像的恢复,其效果受曝光时间内运动距离a的影响较小,可避免频域计算中可能出现的高频振铃现象,实验结果表明,该算法具有较好的恢复效果.
【Abstract】 According to the principle of vehicle motion-blurred image,this article analyzes the degradation model of motion-blurred image,and gives a restoring algorithm which describes the vehicle motion-blurred image in spatial domain.This algorithm doesn’t concern the systematical transfer function,but is based on the inverse process of vehicle motion-blurred image in spatial domain where the image is restored directly.The effect is slightly influenced by the moving distance in the exposure time.Thus,the high frequency vibration phenomenon emerging in the calculation in the frequency domain can be avoided.The experimental results indicate that this algorithm has a satisfying restoring effect.
【Key words】 motion-blurred image; degradation model; image restoration; spatial domain;
