人类在传输压缩视频期间视觉检测分组是否丢失的能力在很大程度上取决于分组丢失的位置和视频的内容。在这篇文章中，我们探索了人类何时可以直观地检测到由单个分组丢失引起的错误。使用基于72分钟视频中1080个丢包率的主观测试结果，我们设计了一个分类器，该分类器使用从视频中提取的客观因素来预测每个错误的可见性。我们的分类器达到了93%以上的准确率。
The ability of a human to visually detect whether a packet has been lost during the transport of compressed video depends heavily on the location of the packet loss and the content of the video. In this paper, we explore when humans can visually detect the error caused by individual packet losses. Using the results of a subjective test based on 1080 packet losses in 72 minutes of video, we design a classifier that uses objective factors extracted from the video to predict the visibility of each error. Our classifier achieves over 93% accuracy.
