Abstract

High Definition video color information research and analysis, mainly considering compression process brought about a decline in the quality of visual perception. Four subjective evaluation is designed and experiments has been done: The diversity of the human eye perception of time; rate selection; and two subjective evaluation experiments of the video with DSCQS as the standard. The High Definition video main characteristics of the human eye perception between color and compression rate injury. Before the experiment, statistical methods were used to calculate the actual sample size; according to R-REC-BT series of standards for subjective evaluation results of the statistical data after the experiment. Finally, analyzed the data results combined with color visual characteristics of the human eye.

高清视频压缩中色彩损伤的视觉感知特征
高清视频色彩信息的研究与分析,主要考虑压缩过程所带来的视觉感知质量的下降。设计了四种主观评价方法并进行了实验:人眼对时间感知的多样性;速度选择;以DSCQS为标准对视频进行两次主观评价实验。高清视频的主要特点是人眼感知色彩和压缩率之间的损伤。实验前采用统计学方法计算实际样本量;根据R-REC-BT系列标准对实验后的统计数据进行主观评价结果。最后结合人眼的色彩视觉特征对数据结果进行分析。
