1. A method of automatically recognizing alphanumeric symbols, comprising:

  • (a) providing a digital representation of a set of unrecognized alphanumeric symbols;

    (b) storing multiple models for each alphanumeric symbol, the models comprising at least one generic model, and at least one exemplar model;

    (c) computing a symbolic representation of each unrecognized alphanumeric symbol comprising a finite set of arcpolys based on the stored alphanumeric symbol models so that the unrecognized symbols can be recognized; and

    (d) providing a set of topological relationships for each pair of arcpolys each comprises a one-of-nine topological connection code and separation, and wherein topological relational features are also automatically classified.
