Abstract: Techniques for estimating speed for an object in a video (either stream or file) are described. In particular, once an object has been recognized, additional data (such as size) for that recognized object is used in a determination of a 3D position of that object in a plurality of frames. An estimated speed may be found using a difference between 3D positions of the object in different frames over the time between the frames.
