Patent

CA 2077970

A method for reducing an image of a character or word string to one or more one dimensional signals, including the steps of determining page orientation, isolating character strings from adjacent character strings, establishing a set of references with respect to which measurements about the character string may be made, and deriving a plurality of measurements with respects to the references in terms of one dimensional signal, amenable to identification processing techniques.

L'invention est une méthode servant à réduire une image d'une chaîne de caractères ou de mots à un signal unidimensionnel ou plus qui comprend les opérations suivantes : détermination de l'orientation de la page, séparation de chaînes de caractères particulières des chaînes de caractères voisines, établissement d'un ensemble de points de référence à utiliser pour les mesures sur les chaînes de caractères, et exécution d'une pluralité de mesures par rapport à ces points de référence à l'aide du signal unidimensionnel. La méthode de l'invention peut être utilisée dans les méthodes d'identification.
