A View-Invariant Representation of Human Action
Cen Rao, Mubarak A. Shah · 2000
The representation plays an important role in recognition and understanding of human action from video sequences. A view-invariant representation of action consisting of dynamic instants and intervals, which is computed using spatiotemporal curvature of a trajectory, is presented. In order to validate our representation, we report experiments on several different actions performed by different people, and captured in different viewpoints.
