Abstract
A surveillance system and method includes imaging means for processing images so that objects in the foreground are detected in the background and threats are identified. In the method, the imaging means acquires images and an initial background model is constructed from those images. Pixels are classified as either background or foreground for subsequent processing stages. In some embodiments, the imaging means is fixed in location and attitude, while in other embodiments, the imaging means is mounted to a moving platform and can alter its attitude. In such mobile applications, the system exploits geo-referencing as an aid in determining information about the pixels.
