摘要

本文研究了高效视频编码(High Efficiency Video Coding, HEVC)压缩程度对观察者检测室外CCTV摄像机视频中特定事件能力的影响。这是通过广泛的主观测试完成的。在相似的比特率下，对H.264/MPEG-4 Part 10 AVC压缩进行了测试，比较了HEVC的检测能力，从而证明了HEVC的优越性。提出了码率增大或量化参数减小均不能提高观测器检测事件能力的情况下编码器的阈值设置。

Influence of HEVC compression on event detection in security video sequences

In this paper, the impact of the degree of compression by High Efficiency Video Coding (HEVC) on observers ability of detecting certain events in videos obtained by outdoor CCTV cameras is studied. This was done by extensive subjective testing. The testing was performed also for H.264/MPEG-4 Part 10 AVC compression on similar bitrates and the capabilities of detection were compared and thus the superiority of HEVC was proven. Also the threshold for encoder setting, where the increase of bit rate or decrease of quantization parameter (QP) do not improve observers ability to detect the events, was proposed.
