Urban video surveillance from airborne and ground-based platforms

摘要

The Analysts' Detection Support System is a flexible processing engine developed to assist the imagery analyst to detect targets in all-source surveillance imagery. It provides the means of structuring a hierarchy of algorithms which, when applied to the data, makes progressively refined decisions on the locations of targets. In particular, we present infrastructure developments which facilitate effective processing of streaming video data, together with an outline of some of the algorithms that have been incorporated to support urban surveillance from airborne and ground-based platforms. These focus on the detection of moving objects and encompass video registration, background modelling and the detection of anomalies.
