We have developed a novel vision system that can recognize people by the way they walk. The system computes optical flow for an image sequence of a person walking, and then characterizes the shape of the motion with a set of sinusoidally-varying scalars. Feature vectors composed of the phases of the sinusoids are able to discriminate among people.
