Abstract

Un dispositif (100) de reconnaissance de caractères manuscrits et un procédé de reconnaissance de caractères manuscrits améliorent la précision des reconnaisseurs de caractères classiques par l'utilisation d'un postprocesseur (130). Le dispositif (100) de reconnaissance de caractères manuscrits comprend un reconnaisseur (100) de caractères, un processeur (140) de modèles de langues comparant les sorties d'un reconnaisseur (120) de caractères à des caractères manuscrits environnants afin de déterminer une probabilité que les sorties dudit reconnaisseur (120) de caractères forment une combinaison avec les caractères manuscrits environnants, et une unité de reclassement (150) qui pondère les probabilités déterminées dans le processeur (140) de modèles de langues avec le reconnaisseur de caractères et reclasse les sorties du reconnaisseur (120) de caractères.
