Abstract

UN METODO DE PROCESO O TRATAMIENTO DE DATOS PARA IDENTIFICAR CARACTERES DESCONOCIDOS DE UN CONJUNTO DE CARACTERES CONOCIDOS BASADO PARCIALMENTE EN LA FRECUENCIA DE OCURRENCIA DE LOS CARACTERES. EL METODO INCLUYE LOS PASOS DE ALMACENAR LOS DATOS DE IMAGEN DE LOS CARACTERES DESCONOCIDOS Y DESPUES APLICAR SECUENCIALMENTE CONJUNTOS DISCRETOS DE PRUEBAS CAPACES DE RECONOCER LOS DATOS E IDENTIFICAR LOS CARACTERES PRIMERAMENTE QUE TIENEN UNA FRECUENCIA MAYOR DE OCURRENCIA. UNA SEGUNDA ETAPA DE PRUEBAS DISCRIMINADORAS ES APLICADA SECUENCIALMENTE A LOS DATOS NO RECONOCIDOS PARA RECONOCER DATOS E IDENTIFICAR CARACTERES QUE TIENEN UNA FRECUENCIA MENOR DE OCURRENCIA QUE EL PRIMER GRUPO DE CARACTERES.
