Motion Descriptor: A Motion Trajectory Signature

摘要：

In this paper, we propose a novel concept of motion descriptor to serve as a fundamental mechanism to describe free form and long-term spatiotemporal motions. The motions are characterized by the underlying motion trajectories extracted via visual tracking. The motion descriptor is a so-called signature description of the motion trajectories. We first present the rationale of the signature definition and its flexible variants. Then the signatures uses for typical computer vision tasks and robot related application are developed. Some experimental results are demonstrated which tests the signatures capability and verifies its effectiveness.
