Abstract

In this paper we propose a general framework for the characterization of shape descriptors and show its application to graphic symbols. The framework is based on the combination of several performance measures independent of the application. We have applied this framework using a standard set of descriptors and databases. We show how it can be used to characterize the properties of each descriptor for a given database.
