Abstract
A content-based video database system requires new technologies to fit the new requirements and characteristics of videos. They include video modeling, query specification, video indexing, and query processing. In this paper, we present Venus, a prototype content-based video database system. Venus consists of a video manger, a query manager, and an indexing tool. The technologies developed for each component are discussed, which include class hierarchies for managing videos and content symbols, a content-based query language for video retrieval, the algorithms for semi-automatic index construction from MPEG coded videos, and the strategies for query processing.
