Abstract
Cameras may be employed to facilitate data collection, to serve as a data source for controlling actuators, or to monitor the status of a process which includes tracking. We proposed an algorithm to explore the temporal relations between trajectory groups in videos, and applied it to action recognition and intelligent human-machine interaction systems. The trajectory components are application-independent features, and function well as mid-level descriptors of actions in videos. The experiments demonstrated performance improvements compared with a pure bag-of-features method. The success of this semantics-free recognition method provides the potential to define high-level actions using low-level components and temporal the relationships between them. This is similar to the way humans perceive and recognize actions.
