论文摘要
每个人都“知道”，压缩视频将降低对象跟踪的准确性。然而，对该主题的文献搜索表明，这一假定事实的证据很少。部分原因是，直到最近，还没有针对未压缩视频的对象跟踪数据集，这使得研究压缩对跟踪准确性的影响变得困难。在本文中，使用最近发布的数据集，该数据集包含未压缩视频的跟踪注释，我们检查了使用严格的统计方法视频压缩而导致跟踪准确性的退化。具体而言，我们检查了量化参数（QP）和运动搜索范围（MSR）对多个对象跟踪精度（MOTA）的影响。结果表明，QP在95％的置信水平上影响MOTA，而没有足够的证据声称MSR会影响MOTA。此外，回归分析使我们能够为实验中使用的特定跟踪器得出MOTA和QP之间的定量关系。
Everyone "knows" that compressing a video will degrade the accuracy of object tracking. Yet, a literature search on this topic reveals that there is very little documented evidence for this presumed fact. Part of the reason is that, until recently, there were no object tracking datasets for uncompressed video, which made studying the effects of compression on tracking accuracy difficult. In this paper, using a recently published dataset that contains tracking annotations for uncompressed videos, we examined the degradation of tracking accuracy due to video compression using rigorous statistical methods. Specifically, we examined the impact of quantization parameter (QP) and motion search range (MSR) on Multiple Object Tracking Accuracy (MOTA). The results show that QP impacts MOTA at the 95% confidence level, while there is insufficient evidence to claim that MSR impacts MOTA. Moreover, regression analysis allows us to derive a quantitative relationship between MOTA and QP for the specific tracker used in the experiments.
