摘要

提出了基于内容的视频查询语言(CVQL)。内容对象的空间和时间关系用于指定查询谓词。现实主义的查询说明,以显示CVQL的力量。支持宏定义以简化查询规范。考虑了CVQL的索引结构和查询处理,实现了一个由图形用户界面和CVQL处理器组成的原型视频数据库系统。用户可以使用GUI绘制查询及其相应谓词的草图,然后可以将查询转换为CVQL进行处理。

A content-based query language for video databases
Presents CVQL (Content-based Video Query Language) for video databases. Spatial and temporal relationships of content objects are used for the specification of query predicates. Queries of realism are illustrated to show the power of CVQL. Macro definitions are supported to simplify query specification. Index structures and query processing for CVQL are considered, and a prototype video database system is implemented, which consists of a GUI and a CVQL processor. Users can sketch a query and its corresponding predicate by using the GUI, and the query can then be converted to CVQL for processing.
