Abstract:
1. A method of automatically recognizing alphanumeric symbols, comprising: (a) providing a set of logical symbols comprising a finite class of arcpolys, wherein the class of arcpolys comprises arcs, lines and points; (b) providing a set of subclass symbols per logical symbol representing a finite subclass of arcpolys, each subclass member having a unique extreme points size and/or depth size; (c) providing a digital representation of a set of unrecognized alphanumeric symbols; (d) automatically classifying the arcpolys of each unrecognized alphanumeric symbol into one or more pairs of logical and subclass symbols such that each unrecognized alphanumeric symbol can be recognized; and (e) providing a set of topological relationships for each pair of arcpolys each comprising a one-of-nine topological connection code and separation, and wherein topological relational features are also automatically classified.
