ABSTRACT:
A pattern recognition system and method wherein errors are reduced by creating independent error templates which correspond to patterns which tend to be erroneously matched and linked error templates which are linked to specified reference templates which are stored for comparison. Upon comparison with reference templates, independent error templates and linked error templates, the unknown pattern is identified as a match wherever its test template is most closely matched to a reference template, is identified as a non-match when its test template is most closely matched with an independent error template, and when most closely matched to a linked error template, the comparison criteria are revised and further comparison(s) are made.
