电影档案中亮度闪烁的修正

针对图像序列中存在亮度闪烁问题，提出一种基于运动补偿的闪烁修正方法，采用三步搜索算法对图像序列进行运动估计，准确地检测出运动区域。运用阈值法对闪烁进行判断，避免非亮度闪烁的误检测。实验结果表明，在准确地修正亮度闪烁的同时，保留原有影片所具有的亮度变化特征。与以往亮度闪烁修正方法相比，在保证影片正常视觉效果的同时缩短了修正时间。

Correction of Intensity Flicker in Film Archived

Aiming at the problem of flicker exists in image sequences, this paper proposes an approach based on motion compensation, it uses three steps search algorithm to estimate motion vectors, which can detect motion regions more accurately. Threshold method to detect flicker, avoide non-flicker regions in painting, and improve the efficiency. Experimental results show that with the accurate correction of intensity flicker, the proposed algorithm can preserve the wanted effects with similar features, and shorten the time of intensity flicker correction.
