Abstract
A surveillance and control system includes a feature extraction unit to dynamically extract low-level features from a compressed digital video signal, a description encoder, coupled to the feature extraction unit, to encode the low-level features as content descriptors. An event detector is coupled to the description encoder to detect security events from the content descriptors, and a control signal processor, coupled to the event detector, to generate control signals in response to detecting the security events.
