<p>A pattern recognition apparatus includes a plurality of net structure dictionaries, reconstruction section, a first storage section, and a pattern matching section. Each of the net structure dictionaries has a net structure formed by connecting, through a node, a parent arc representing a common portion of a plurality of standard patterns as recognition units of a recognition target to a child arc representing a remaining portion. The reconstruction section extracts a common structure from the net structure dictionaries and reconstructs them to generate a reconstructed dictionary. The first storage section stores original dictionary connecting information representing the relationship between the extracted common structure and the net structure dictionaries. <IMAGE></p> |
