| 摘 要： | 保存和修复旧电影是非常迫切的一项任务。在电影修复过程中，闪烁去除是经常遇到的一个问题。然而大多数闪烁去除算法中并没有考虑局部运动造成的影响。基于这一点，该文提出了一种采用余弦基和逐次超松弛迭代法的闪烁去除方法。方法中充分考虑了局部闪烁和局部运动的影响，在对实际旧电影图像处理中达到了比较满意的效果。

| Abstract: | It is extremely needed to conserve and restore old films. Intensity flicker is a common artifact in old black-and-white film sequences. Unfortunately, the existing algorithms removing intensity flicker do not consider the effect of local motion. To improve this points a method based on the cosine basis and the successive over-relaxation is developed in this paper. Both local motion and local flicker are considered in this method. Experiments for real-world old film sequences shows that the result is satisfactory. |
