# Using Discrimination Graphs to Represent Visual Interpretations that are Hypothetical and Ambiguous

Jan A. Mulder

*Proceedings of the Ninth International Joint Conference on Artificial Intelligence*, pages 905-906.

## Abstract

The use of specialization hierarebiet in model-based vision systems may cause problems with uniformity in representation and efficiency. The concept of a discrimi· nation graph is introduced. Such a graph facilitates the representation of hypothetical and ambiguous interpreta· tions in a unifonn and efficient way. We describe the implementation of Mapsee-3, a sketch map interpreta· tion program that uses discrimination graphs in combination with a hierarchical constraint propagation algorithm .
