摘要： 给一段黑白的视频着上彩色是图像处理方面一个比较热门的方向，能得到使人惊奇的视觉效果。文章引入一种颜色空间(lαβ)，首先根据参考彩色图像，比较参考彩色图像和黑白视频中的第一帧的亮度的差异，把参考彩色图像上的颜色信息传输到这幅黑白图像上。提出了一种快速的相邻帧图像基于亮度比较的物体运动预测方法，跟踪物体的运动，从而给物体着上合适的颜色。

Abstract: Transferring color to grayscale image is an important topic in the area of image processing, which results in amazing visual effect. This paper introduces a color space(lαβ). At first, it compares the achromatic difference between color reference image and the first frame of video clip, and transfers the chromatic information of the matching pixel to the grayscale image. A rapid algorithm is proposed to track the movement of objects based on the comparison of illumination and the appropriate color is added to them.
