Abstract:
Video databases have both spatial and temporal components. Querying and retrieval of spatio-temporal content is a challenging task due to lack of simple user interfaces. In this paper, we propose a system to allow the user to interactively build “eventually” queries in video databases. In eventually queries, the user just needs to provide the starting state (or information) and the ending state without providing the intermediate states. This helps the user setup queries without knowing all details. Our system uses a methodology similar to the one in gaming. Queries are built by displaying natural videos based on gamepad commands rather than on a graphical interface using a mouse or a keyboard. The system uses a semantic sequence state graph (S3G) to search the database. The system is applied on a tennis video database. This paper, proposes a novel spatio-temporal query and retrieval system with user friendly interface for developing “eventually” type spatio-temporal queries using gamepad.
