Abstract

A method for the recognition of handprinted characters, based on their structural description, is illustrated. Special importance is given to the procedure for decomposing characters into elementary components. The first aim, in fact, is to obtain descriptions as much as possible invariant with respect to the large shape variations existing among handprinted characters. The descriptions, given in terms of relational attributed graphs, are eventually matched against prototypes by using heuristic matching criteria that imply the contextual use of rules for transforming, with measurable costs, similar graphs into one another. Preliminary tests of performance have given stimulating results. Large scale experiments are now running.
