Conceptual descriptions from monitoring and watching image sequences

This paper contrasts two ways of forming conceptual descriptions from image s. The first, called "monitoring", just follows the flow of data from image s to interpretation, having little need for top-level control. The second, called "watching", emphasizes the use of top-level control and actively sel ects evidence for task-based descriptions of the dynamic scenes. Here we lo ok at the effect this has on forming conceptual descriptions. First, we loo k at how motion verbs and the perception of events contribute to an effecti ve representational scheme. Then we go on to discuss illustrated examples o f computing conceptual descriptions from images in our implementations of t he monitoring and watching systems. Finally, we discuss future plans and re lated work. (C) 2000 Elsevier Science B.V. All rights reserved.
