论文摘要
测量视频质量的黄金标准是主观测试，最普遍的是ITU-T REC。 P.910，过去二十年来使用的基于实验室的主观标准。但是，实际上使用itu-t rec。 p.910很慢，昂贵，需要一个实验室，所有实验室都造成了使用障碍。结果，大多数需要测量视频质量的研究论文不使用ITU-T REC。第910页，但与主观意见相关的指标。我们提供ITU-T REC的开源扩展。第910页，基于众包原则，该原则涉及使用速度，使用成本和使用问题的障碍。我们实现绝对类别评级（ACR），具有隐藏参考（ACR-HR），降解类别评分（DCR）和比较类别评级（CCR）的ACR。它包括评估者，环境，硬件和网络资格，以及黄金和诱捕问题，以确保质量。我们已经验证了与现有ITU-T REC相比，该实施既准确又高度可重复。 p.910实验室研究。
The gold standard for measuring video quality is the subjective test, and the most prevalent is the ITU-T Rec. P.910, a lab-based subjective standard in use for the past two decades. However, in practice using ITU-T Rec. P.910 is slow, expensive, and requires a lab, which all create barriers to usage. As a result, most research papers that need to measure video quality don't use ITU-T Rec. P.910 but rather metrics that are not well correlated to subjective opinion. We provide an open-source extension of ITU-T Rec. P.910 based on crowdsourcing principles which address the speed, usage cost, and barrier to usage issues. We implement Absolute Category Rating (ACR), ACR with hidden reference (ACR-HR), Degradation Category Rating (DCR), and Comparison Category Rating (CCR). It includes rater, environment, hardware, and network qualifications, as well as gold and trapping questions to ensure quality. We have validated that the implementation is both accurate and highly reproducible compared to existing ITU-T Rec. P.910 lab studies.
