Abstract
A system and method for hypervideo object tracking in a compressed digital video environment includes a hypervideo authoring system and a hypervideo browser. The hypervideo authoring system permits one or more moving objects in an MPEG compressed video clip to be identified, tracked, refined, edited, and associated with a specified action with a minimum of user intervention. The hypervideo browser allows the MPEG video to be viewed and objects of interest to be selected by a user, thereby hyperlinking to additional information of interest.
