Abstract : In this paper, we address the use of unified spatial relations for symbol description. We present a topologically guided directional relation signature. It references a unique point set instead of one entity in a pair, thus avoiding problems related to erroneous choices of reference entities and preserves symmetry. We experimentally validate our method on showing its ability to serve in a symbol retrieval application, based only on a spatial relational descriptor that represents the links between the decomposed structural patterns called “vocabulary” in a spatial relational graph.
