摘　　要：当前,从海量监控视频中高效、准确地提取关键帧是一项极具挑战性的课题,为此提出了一种基于运动轨迹分析的监控视频关键帧提取方法。给出了该方法的实现过程,并进行了实验与分析。结果表明,所提出的方法在关键帧提取准确性上优于当前的主流方法。Currently, efficient and accurate key frame extraction for massive videos remains a challenge, especially in surveillance applications. Motivated by this observation, a method for surveillance video key frame extraction based on motion trajectory analy- sis is proposed. The implement of the proposed method is given, and the performances are compared with the state-of-the-art method. Experimental results have demonstrated that the proposed method outperforms existing state-of-the-art method in terms of accuracy for key frame extraction.
