| 摘 要： | 针对多视点视频系统中视点间颜色不一致,给后续多视点视频编码和虚拟视点绘制带来困难的问题,提出一种面向编码和绘制的多视点视频颜色校正方法.首先采用连续多帧求帧差法提取出各个视点图像的背景区域,再利用背景区域计算校正因子,对颜色不一致的视点进行颜色校正.实验结果表明,该算法不仅能实现视点间图像的颜色一致性,提高多视点视频的编码效率,而且提高了虚拟视点绘制性能,是一种有效的多视点视频系统颜色校正方法.

| Abstract: | In order to solve the problem of inconsistent color appearance between different views,and subsequently influences on multi view coding and view rendering,a multi view video color correction algorithm is proposed.Firstly,background region in each view is extracted by using successive frames differences.Then correction factors are estimated from the extracted background.Finally,color correction is achieved.Experimental results show that the proposed algorithm can obtain consistent color appearance for different views and high coding efficiency and improve the performance of virtual view rendering,thus it is an effective method for color correction. |
