【摘要】 在车载监控过程中,为提高视频检索的效率,提出了一种快速检索方法。首先,采用一种改进的基于块匹配的方法快速消除视频抖动,完成图像序列预处理;然后根据不同用户需求,通过自动和主动两种方式检索视频。实验结果表明,该方法在不遗漏重要画面的同时,能够快速检索到用户感兴趣的视频片段,为用户减少了大量的视频浏览时间。更多还原

【Abstract】 In the on-board monitoring process,to improve the browsing efficiency of surveillance video,a fast retrieval video method is proposed.Firstly,using a kind of new algorithm based on blocks matching to quickly eliminates jitter.This can realize pretreatment of image sequence.Then,automatic and active retrieval ways are used to meet different needs of the user retrieval.The experimental results show that this method can not miss important in picture at the same time,and can access fast to users interested in video clips,for a large number of video browsing users to reduce the time.更多还原
