Abstract
A novel video object extraction has a first object 12, such as a foreground object, illuminated with visible light 16 and a second object 14, such as a background object, illuminated with a combination of infrared 18 and visible light 16. A novel camera system observes the scene. The novel camera system includes an infrared light camera 24 and a visible light camera 20. The infrared light camera output 24 contains bright images of the second object 14, with relatively little brightness of the first object 12. The signal from this infrared light camera 20, once thresholded, serves as a key to remove the second object 14 from the video image captured by the visible light camera 20.
