A Relational Indexing Method for Symbol Spottingnd. In order to foster the querying speed, a hashing technique is proposed which is able to retrieve very efficiently primitives by similarity. Vectorial primitives are coarsely encoded by well-known shape description methods providing a numerical description of the primitives. A relational indexing

Performance Evaluation of Symbol Spotting Systemsey shall have the ability to recognize and locate graphical symbols in a single step. In this chapter, we present a set of measures to evaluate the performance of a symbol spotting system in terms of recognition abilities, location accuracy and scalability. We show that the proposed measures allow d

Then, the existing data structures which aim to store the extracted descriptors and provide efficient access to them will be analyzed. We finally review the existing methods for hypotheses validation which can be used for spotting purposes.

A Relational Indexing Method for Symbol Spotting approach is presented in order to introduce some structural information of the symbols and provide an accurate hypotheses validation. Experimental results show the performance of the proposed approach.
