Abstract

An earlier article [*] describes a recognition system for cursive writing based on elastic matching of the unknown word against a set of letter prototypes. The input to the system is point data produced by the dynamic trace of a stylus on an electronic tablet. Processing is performed on a word-by-word basis after the writing is separated into words. Using prototypes for each letter, the matching procedure allows any letter to follow any letter and finds the letter sequence which best fits the unknown word. Because the unknown word is matched with a direct concatenation of letter prototypes, it must be possible to partition the time sequence of strokes into letters.
