ABSTRACT:
An elastic-matching alignment technique for providing an averaged prototype in a handwriting recognition system that improves the alignment of parametric representations of recognized characters to be averaged. The point-to-point correspondence resulting from an elastic match of two characters is obtained by using backpointers during the calculation of the match. A character is added to a prototype set if it is new or is not correctly recognized within a fixed threshold. Otherwise, the character is averaged into the closest prototype of its class to provide a new average prototype.
