Abstract:
A consumer-grade camera is used to view the motion of individuals moving in an area, such as that observed in the lobby of a building. By assuming individuals are engaged in fairly normal walking behavior, we can extract sufficient information to synthetically reconstruct the scene using simple image processing techniques. The reconstructed scene can then be viewed from any angle and used to track interesting individuals. Features of the person such as shirt and pants color can be extracted from the video and applied to the synthetic model thus allowing the real individual to be recognized from viewing the reconstruction. The technique proposed has the advantage of using a single camera and would find applications in gait analysis and security. This is a work in progress and we present some initial results of a single moving figure.
