A handwritten character recognizing device (100) and method for handwritten character recognition improves the accuracy of conventinal character recognizers by using a post-processor (130). The handwritten character recognizing device (100) includes a character recognizer (120), a language model processor (140) which compares outputs from the character recognizer (120) with surrounding handwritten characters to determine a probability that the outputs from the character recognizer (120) would be in combination with the surrounding handwritten characters, and a resorter (150) which weights the probabilities determined in the language model processor (140) with the character recognizer and resorts the character recognizer (120) outputs.

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.
