1. A method for translating a graphic element into a machine readable character, said method comprising the steps of:

  • defining a plurality of sets of machine readable characters, each of which contains machine readable characters of a unique type;

    generating descriptors for said machine readable characters in each of said sets of machine readable characters;

    generating descriptors for said graphic element; and

    for each one of said plurality of sets of machine readable characters, performing recognition on said graphic element by;

    comparing said descriptors of said graphic element to said descriptors of said machine readable characters in said one of said plurality of sets of machine readable characters in order to determine whether any of said machine readable characters in said one of said plurality of sets of machine readable characters matches said descriptors of said graphic element using predetermined match criteria that are substantially the same for each of said plurality of sets of machine readable characters; and

    when said comparing step determines that said descriptors of at least one of said machine readable characters in said one of said plurality of sets of machine readable characters matches said descriptors of said graphic element, identifying for each one of said plurality of sets of machine readable characters one of said machine readable characters in said one of said plurality of sets of machine readable characters that matches said descriptors of said graphic element.
