ABSTRACT:
A method, and apparatus for accomplishing same, of providing character prototypes for use by a handwriting character recognition system 10. A first method includes a first step of providing a first handwritten character; a second step of copying the first character to provide a second character; and a third step of modifying the second character to (a) emphasize dissimilarities between the second character and the first character and to (b) de-emphasize similarities between the second character and the first character. A second method includes a first .step of providing a first handwritten character and a second handwritten character, the first and the second handwritten characters each being comprised of a plurality of points. A second step of the method matches corresponding points between the first character and the second character. A third step of the method processes pairs of matching points to separate one from another each point of the matching pair by an amount proportional to an initial separation between each matched corresponding point, so as to emphasize dissimilarities between the first character and the second character.
