Computer vision face tracking for use in a perceptual user interface

Posted: 21 Dec 1999 ?? ?Print Version ?Bookmark and Share

Keywords:camshift? continuously adaptive mean shift? tracking? intel? hsv?

As a first step towards a perceptual user interface, a computer vision color tracking algorithm is developed and applied towards tracking human faces. Computer vision algorithms that are intended to form part of a perceptual user interface must be fast and efficient. They must be able to track in real time yet not absorb a major share of computational resources: other tasks must be able to run while the visual interface is being used. This application note discusses the mode of a color distribution within a video scene using the Continuously Adaptive Mean Shift (CAMSHIFT) algorithm.
