Abstract

L'invention concerne un dispositif de détection et de localisation de caractères sur la surface d'un document. Les caractères sont détectés par des capteurs qui produisent un train d'information binaire mis en circulation dans un registre à décalage. Des chercheurs déclenchés sur une base de priorité examinent et poursuivent les données qui passent par une fenêtre fixe du registre. Les informations recueillies qui satisfont une condition de départ et une condition de contiguité sont mémorisées, et les informations provenant de plusieurs chercheurs sont fusionnées dans une mosaïque en mémoire pour être utilisées par un dispositif de reconnaissance de caractères. L'invention s'applique à la lecture automatique de documents imprimés.
