| Abstract(in English) | The traditional adding template method has a serious flaw in that the recognition rate of learnt patterns decreases as dictionary learning progresses. To solve this problem, we present a hierarchical system that outputs the recognition result from Voronoi regions given by reference templates as the first candidate. Next, hyperspherical classifiers given by the addition of templates generated in the Voronoi region determine the correct candidate. The hierarchical system promotes the recognition rate by dictionary learning and succeeds in overcoming the problem in experiments on handwritten Kanji pattern recognition. |
