视频目标识别是国防和民用领域的重要课题。然而，在当前的视频编码标准H. 264中没有考虑对象识别保证。针对这一问题，本文设计了基于H. 264/AVC编解码器的实验，研究了编码参数对识别性能的影响。给出了识别性能与编码率和分辨率的定量函数。更实际地，当需要高效的视频数据传输时，这样的函数可以用于信道带宽和视频对象识别性能之间的最佳折衷。
Video object recognition is an importance topic in both defense and civilian applications. However, object recognition guarantee is not considered in current video coding standard H.264. For this issue, experiments based on H.264/AVC codec are designed to measure the affection of coding parameters on recognition performance. The quantitative functions of recognition performance with coding rate and resolution ratio are given. More practically, such functions can be used for optimal tradeoff between the channel bandwidth and video object recognition performance when efficient video data transfer is needed.
