Method for automatically following the movements of a hand in a sequence of images

摘要

The method involves receiving an image stream in real time, and locating a contour (CT) of a hand in each image of the stream, where the contour delimits an image zone (HA) of the hand. A pixel of the image zone faraway from the contour is searched for locating the center of palm (PC) of the hand in the image zone in order to extract postural characteristics of the hand from the zone. Movements of the hand in the image stream are determined from the extracted postural characteristics. An independent claim is also included for a device for monitoring movements of a hand in an image stream.
