Interactive Digital Mirror

This paper describes some preliminary results of our ongoing project on digital mirror interfaces. Regular mirrors reflect ambient light from the scene towards the observer. Digital mirrors capture the ambient light with a camera, extract information about the scene, and display appropriate information to the user, combining real-time computer vision systems with realistic computer graphics. We describe the works on both ends, image processing from the camera, and image output to a computer screen. The computer vision routines developed so far are basically for human face detection, tracking and 3D head pose estimation. The main computer graphics routines are able to render a 3D head model in real-time. We are starting to integrate both ends, and coding very simple behaviors to the virtual head.
