| 摘 要： | 新闻视频研究与服务要求每天从各种电视台采集大量的新闻节目.为了节省存储空间和方便分析,要先去除新闻视频中的非新闻段(商业广告、频道/节目标识等).本文采用探测视频流中重复镜头的方法来进行此项工作.首先将新闻视频分割为镜头,再对镜头进行聚类,选择出候选的非新闻镜头聚类,然后对候选镜头进行相同镜头匹配,匹配成功的镜头即为重复的非新闻镜头.相比为其他类似问题的研究(主要是探测商业广告),该方法计算量小,不需要先验假定条件,而且实验结果令人满意.

| Abstract: | Research and service of news video demand recording volumes of news programs from many TV stations.For saving storage space and for the convenience of analysis,non-news parts(e.g.commercial and channel/program logo)of news video should be removed firstly.This paper removes non-news parts based on detecting repeating shots.First,news video is segmented into shots.Then,shots are clustered and some shot clusters are chosen as candidates of non-news shots.Finally,candidate shots are compared between each other and matched shots are removed as non-news shots.Compared with other similar study(mainly on commercial detecting),this method needs much less computation and no prior assumption.Experimental test showed this method is satisfying. |
