	abstract = {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.
