what: ofxMotionTemplates is an OpenFrameworks addon that enables developers to simply create computer vision interfaces controlled by motion; it makes use of MIT’s Media Lab Motion Templates algorithm to find moving objects inside a video stream and keeps track of the motion history of every found object. The data recorded by the library can be used to track movement inside a video, use natural body motion to control software, understand gestures performed in front of a camera, etc…
