Abstract

A gesture recognition process includes tracking an object in two frames of video, determining differences between a location of the object in one frame of the video and a location of the object in another frame of the video, obtaining a direction of motion of the object based on the differences, and recognizing a gesture of the object based, at least in part, on the direction of motion of the object.
