Real-time tracking movements using a video camera and a position sensor.

Abstract:
This paper describes a real-time tracking movement system running on a Silicon Graphics Indy station. It deals more particularly with the data fusion from a position sensor and a standard color camera so as to speed up processing. Variations of the shape of the hand are taken into account using an active contour model, and the motion of the hand is detected by the position sensor.
We describe a method to find local deformations by segmentation, filtering and moving of an active contour. We will also account into details for the use of global deformations allowing to follow the user's fast moves. That last point implies a calibration of the camera-sensor couple to known the location of the sensor in the image at all times.
Keywords: Active contour, Data fusion, Hand tracking, Image processing, Position sensor.
