A method and system for effectively performing event detection in a large number of concurrent image sequences

Abstract From the Canadian patent

Method and system for performing event detection and object tracking in image streams by installing in field, a set of image acquisition devices where each , device includes a local programmable processor for converting the acquired image stream that consist of one or more images to a digital format, and a , local encoder for generating features from the image stream. These features are parameters that are related to attributes of objects in the image stream. The encoder also transmits a feature stream whenever the motion features , exceed a corresponding threshold. Each image acquisition device is connected to a data network through a corresponding data communication channel. An image …
