摘要

本文对来自两个公开视频数据集的压缩高分辨率视频序列进行了五种全参考客观质量评价方法的性能分析。在绩效分析中采用了国际研究界公认的量化指标——等级相关系数和主客观质量分数之间的线性相关系数。性能分析是全局进行的-完整数据集的级别和具有共同特征(压缩类型或源序列)的序列子集。分析了三种类型的压缩视频内容——H.265及其前身H.264和MPEG-2。分析了视频信号在不同尺度(分辨率)下主客观质量分数之间的相关性。通过对结果的分析,得出了压缩视频信号客观质量评价的重要结论,并提出了进一步工作的方向。

Comments on Objective Quality Assessment of MPEG-2, H.264 and H.265 Videos
This paper presents the performance analysis of five full-reference objective quality assessment measures on compressed high-resolution video sequences from two publicly available video datasets. Quantitative measures that were accepted by the international research community used in the performance analysis - the correlation coefficient of ranks and the linear correlation coefficient between subjective and objective quality scores. The performance analysis is carried out globally - the level of complete datasets and on subsets of sequences with common characteristics (compression type or source sequence). Three types of compressed video content were analyzed - H.265 and its predecessors H.264 and MPEG-2. The correlation between subjective and objective quality scores is analyzed in different scales (resolutions) of the video signal. From the analysis of the results, very important conclusions on the objective quality assessment of the compressed video signals were derived, as well as the directions for further work.
