Abstract

The invention is directed to a pattern recognition apparatus and method by which an unknown input pattern is divided into a plurality of sub-area patterns which are matched with a plurality of standard partial characteristic patterns to form an input pattern similarity matrix F. The input pattern similarity matrix is then matched with a plurality of reference similarity matrices .PHI.l of standard reference patterns, whereby the unknown pattern is recognized as the one of the L standard reference patterns which gives the best matching.
