摘　　要：本文基于视频特征,对电视广告单元分割技术进行了研究。对广告视频的检测算法框架流程展开深入分析。综合切变镜头检测算法以及消隐镜头,结合区域特征重要性对其进行划分,形成不同的镜头合集,在分类特征的基础上提取镜头。并分析了视频广告在时间、内容上的连续性,此外完善了广告镜头后期处理机制,全面消除错误镜头。此外还专门制定了镜头整合算法。此外还专门制定了镜头整合算法,合并广告镜头,以产出广告视频片段。Based on video characteristics,this paper studies the segmentation teciinology of TV advertising unit.The frame flow of detection algorithm for advertising video is analyzed.The vicieo segment is segmented into a set of sliots,which is based on the importance of regional feature,and extracts the classification features based on the lens.The continuity of video advertisement in time and content is analyzed,and the post processing mechanismof accumulative advertising lens based on sliding window is put forward to eliminate some error shots.And the lens integration algorithm is proposed to merge the advertising lens to get advertising video clips.
