A Petri Net Based Method for Extracting Events from Surveillance Video
Guohui Li · Video Engineering · 2006
With an extended definition of Petri net, this paper proposes a Petri net based representation scheme of the spatio-temporal relations and events in surveillance video. By mapping high-level semantic queries into a Petri net and inferring with interpretations of moving objects using low-level computer vision algorithms, events about activities of moving objects are inferred and the relevant video clip is well located.
