Digital Video Event Detector Framework for Surveillance Applications

The paper introduces a video surveillance and event detection framework and application for semi-supervised surveillance use. The system’s intended use is in automatic mode on camera feeds that are not actively watched by surveillance personnel, and should raise alarms whenunusual events occur. We present the current detectorfilters, and the extendable modular interface. Filters include local and global unusual motion detectors,left/stolen object detector, motion detector, tampering/failure detector, etc. The system stores the events and associated data, which can be organized, searched, annotated and (re)viewed. It has been tested in real life situation for police street surveillance.
