Using a detect and track paradigm, we present a surveillance framework where each camera uses local resources to perform real-time person detection. These detections are then processed by a distributed site-wide tracking system. The detectors themselves are based on boosted user-defined exemplars, which capture both appearance and shape information. The detectors take integral images of both intensity and Sobel responses as input. This data representation enables efficient processing without relying on background subtraction or other motion cues. View-specific person detectors are constructed by iteratively presenting the boosting algorithm with training data associated with each individual camera. These detections are then transmitted from a distributed set of tracking clients to a server, which maintains a set of site-wide target tracks. Automatic calibration methods allow for tracking to be performed in a ground plane representation, which enables effective camera handoff. Factors such as network latencies and scalability will be discussed. © 2007 IEEE.
