摘要
针对现有视频数据库系统存在的不足,根据视频数据的特点,提出并实现了一种基于MPEG-7标准的视频数据组织与管理方法.该方法将视频内容的描述数据按照不同层次的视频内容单元进行组织,并针对不同的描述数据,分别生成结构索引、文本索引和特征索引,以满足基于内容的视频浏览和检索的需求.实验证明,通过视频描述数据库对视频数据进行管理,不仅降低了服务器的存储要求,而且为基于内容的视频检索奠定了基础,具有很好的通用性和可扩展性.
According to the intrinsic characteristics of video data,a video organization and management method has been proposed and implemented based on MPEG-7 standard,and it has very good versatility and scalability.Video description data are stored in video description database according to difference video content units which are organized by hierarchical mode.And more,video structure indexing,text indexing and feature indexing are constructed for video browse and retrieval.Vast amounts of video data distrusted on the network are effectively managed through video description database.It not only reduces the server＇s storage requirements,but also lays a good foundation for the future Content-Based Video Retrieval.
