大部分的视觉质量评估的工作一直致力于灰度图像，考虑到颜色信息和时间分量的度量仍然相对罕见。本文提出了一种基于人类视觉系统的对比度增益控制模型的彩色视频质量度量。它用于评估MPEG编码序列的质量，并表现出与主观评级一致的行为。
Much of the work on visual quality assessment has been devoted to gray-level images; metrics taking into account color information and the temporal component are still relatively rare. This paper presents a quality metric for color video which is based on a recent contrast gain control model of the human visual system. I t is used to assess the quality of MPEG-coded sequences and exhibits a behavior that is consistent with subjective ratings.
