摘要： The present invention relates to a technique for optimizing off-line facial feature tracking. Facial features in a sequence of image frames are automatically tracked while a visual indication is presented of the plurality of tracking node locations on the respective image frames. The sequence of image frames may be manually paused at a particular image frame in the sequence of image frames if the visual indication of the tracking node locations indicates that at least one location of a tracking node for a respective facial feature is not adequately tracking the respective facial feature. The location of the tracking node may be reinitialized by manually placing the tracking node location at a position on the particular image frame in the monitor window that corresponds to the respective facial feature. Automatic tracking of the facial feature may be continued based on the reinitialized tracking node location.
