| Abstract(in English) | In this report,accuracy improvement of handwritten numeral recognition, by adding the curvature feature obtained from gray scale contour to the direction feature of the gradient, is discussed.For dimension reduction of feature vector, the FKL(Fisher-Karhunen-Loeve)method, a generalization of the canonical discriminant analysis and the principal component analysis is shown to be most effective. The high recognition rate of 99.30% is achieved for handwritten numeral data base "IPT CDROM1" distributed by IPTP(Institute for Posts and Telecommunications Policy). |
