TY - JOUR T1 - Mining tool for surveillance video JF - SPIE 16th International Symposium on Electronic Imaging, Storage and Retrieval Methods and Applications for Multimedia Y1 - 2004 A1 - Ghanem,N.M. A1 - David Doermann A1 - Davis, Larry S. A1 - DeMenthon,D. AB - This paper describes a system for the mining of surveillance video. Our main contributions are: providing ahigh level query language for submitting queries about spatial and temporal relations of background regions and moving entities, and about human activities; providing a compiler to map high level queries into a set of novel Petri net filters that utilize computer vision algorithms to answer components of the queries; and providing a powerful graphical interface where users have the ability to formulate the query visually.
