This paper contrasts two ways of forming conceptual descriptions from images. The first, called “monitoring”, just follows the flow of data from images to interpretation, having little need for top-level control. The second, called “watching”, emphasizes the use of top-level control and actively selects evidence for task-based descriptions of the dynamic scenes. Here we look at the effect this has on forming conceptual descriptions. First, we look at how motion verbs and the perception of events contribute to an effective representational scheme. Then we go on to discuss illustrated examples of computing conceptual descriptions from images in our implementations of the monitoring and watching systems. Finally, we discuss future plans and related work.
