Abstract

A systematic method for recognizing the contents of a video through the help of some panoramas recorded in a database is proposed in this paper. A panorama inherently records the appearances of an omni-directional scene from its center point to arbitrary viewing directions, and thus can serve as a compact representation of an environment. The associated recognition task is formulated as a shortest-path search problem, and a dynamic-programming technique is used to solve it. Experimental results show that our method can recognize a video effectively.
