点评：一种多视点视频的颜色校正方法，包括：通过计算目标图像和源图像直方图，利用动态规划算法求取最小成本路径，从而建立源图像和目标图像间的颜色映射关系，并通过在水平和垂直方向增加补偿因子来保证路径的平滑，最后通过视频跟踪技术实现对多视点视频颜色校正，本发明在保证多视点视频颜色校正精确性的前提下，大大提高了颜色映射的精度，降低了多视点视频颜色校正的计算复杂度，避免了在颜色映射过程中区域边界出现色彩不连续的情况，消除了边缘失真，提高了多视点视频颜色校正的速度和精度。

Comment: This invention discloses a color correction method of videos of multiple viewpoints including: computing the histograms of a target imafe and a source image, utilizing a dynamic programming algorithm to seek the minimum cost path so as to set up a color mapping relation between the two images, besides, it increases compensation factors on the level and vertical directions to ensure smooth of the path and finally to realize color correction to videos of multiple viewpoints by a video follow technology to increase the mapping accuracy of colors.
