Abstract

This paper is dedicated to the analysis of the existing approaches to video codecs comparisons. It includes the revealed drawbacks of popular comparison methods and proposes new techniques. The performed analysis of user-generated videos collection showed that two of the most popular open video collections from media.xiph.org which are widely used for video-codecs analysis and development do not cover real-life videos complexity distribution. A method for creating representative video sets covering all segments of user videos the spatial and temporal complexity is also proposed. One of the sections discusses video quality estimation algorithms used for video codec comparisons and shows the disadvantages of popular methods VMAF and NIQE. Also, the paper describes the drawbacks of the BD-rate – generally used method for video codecs final ranking during comparisons. A new ranking method called BSQ-rate which considers the identified issues is proposed. The results of this investigation were obtained during the series of research conducted as part of the annual video-codecs comparisons organized by video group of computer graphics and multimedia laboratory at Moscow State University.

BSQ速率：视频编解码器性能比较和当前解决方案缺点的一种新方法

摘要

本文致力于分析视频编解码器比较的现有方法。它包括了流行的比较方法的缺点，并提出了新的技术。对用户生成的视频集合进行的分析表明，来自media.xiph.org的两个最受欢迎的开放视频集合（广泛用于视频编解码器分析和开发）并不涵盖现实生活中的视频复杂性分布。还提出了一种用于创建代表性视频集的方法，该代表性视频集覆盖了用户视频的所有片段，具有时空复杂性。这些部分之一讨论了用于视频编解码器比较的视频质量估计算法，并说明了流行方法VMAF和NIQE的缺点。也，本文介绍了BD速率的缺点-BD速率通常用于比较期间的视频编解码器最终排名。提出了一种新的名为BSQ-rate的排序方法，该方法考虑了已识别的问题。这项调查的结果是在莫斯科国立大学计算机图形学和多媒体实验室视频小组组织的年度视频编解码器比较研究过程中获得的。
