# Model Representations and Control Structures in Image Understanding

*Proceedings of the Fifth International Joint Conference on Artificial Intelligence*, pages 1074-1081.

## Abstract

This paper overviews and discusses model repr e sentations and control structures in image understanding. Hierarchies are observed in the levels of description used in image understanding along a few dimensions: processing unit, detail, composition and scene/view distinction. Emphasis is placed on the importance of explicitly handling the hierarchies both in representing knowledge and in using it. A scheme of "knowledge block" representation which is structured along the processing-unit hierarchy is a lso presented.
