Video motion representation for improved content access
S. Jeannin, B. Mory · IEEE Transactions on Consumer Electronics · 2000
This paper describes techniques for representing motion information in the context of multimedia description interfaces (being standardized by MPEG-7). Focusing on camera motion and object trajectories, it explains how to extract the descriptions from the content, and express them in a compact way. It also shows how such descriptions can help consumers to browse and query through large audiovisual collections.
