Method and apparatus for handwriting recognition system for ideographic characters and other characters based on subcharacter hidden Markov models. The ideographic characters are modeled using a sequence of subcharacter models and by using two-dimensional geometric layout models of the subcharacters. The subcharacter hidden Markov models are created according to one embodiment by following a set of design rules. The combination of the sequence and geometric layout of the subcharacter models is used to recognize the handwriting character.

Cette invention concerne un procédé et un appareil permettant de créer un système de reconnaissance de caractères idéographiques ou d'autres caractères mettant en oeuvre des modèles de sous-caractères fondés sur la modélisation markovienne. Les caractères idéographiques sont modélisés en utilisant une séquence de modèles de sous-caractères et des modèles de présentation géométrique bidimensionnelle desdits sous-caractères. Dans une forme d'exécution, les modèles de sous-caractères fondés sur la modélisation markovienne sont créés suivant un ensemble de règles de conception. La combinaison de la séquence et de la présentation géométrique des modèles de sous-caractères permet la reconnaissance de caractères manuscrits.
