Spatial relationships are important ingredients for expressing constraints in retrieval systems for pictorial or multimedia databases. We have proposed a unified representation for spatial relationships, 2D Projection Interval Relationships (2D-PIR), that integrates both directional and topological relationships. In this paper we develop techniques for similarity retrieval based on the 2D-PIR representation. The results of experiments with a prototype show that 2D-PIR is a promising approach for similarity retrieval of images.
