Abstract
SE PRESENTA UN METODO Y UN SISTEMA PARA DECODIFICAR UN SIMBOLO OPTICO BIDIMENSIONAL EN EL DOMINIO ESPACIAL. EL SISTEMA DETERMINA LA ORIENTACION DE UN SIMBOLO DE LA IMAGEN EN EL DOMINIO ESPACIAL MEDIANTE LA UTILIZACION DE UNA PLANTILLA PARA DERIVAR UN COEFICIENTE DE CORRELACION ENTRE LAS SEÑALES ADYACENTES RADIALMENTE EN UN ANGULO DADO DE LA PLANTILLA Y MEDIANTE LA COMPARACION DE LOS COEFICIENTES DE CORRELACION AL TIEMPO QUE SE GIRA A LA PLANTILLA CON RESPECTO A LA IMAGEN. EL ANGULO DEL COEFICIENTE DE CORRELACION MAS ALTO SE CORRESPONDE CON LA ORIENTACION DE UN CONJUNTO DE EJES DEL SIMBOLO QUE INCLUYEN ELEMENTOS CONTIGUOS CUYOS CENTROS ESTAN COALINEADOS. ENTONCES, EL SISTEMA COLOCA CADA ELEMENTO INDIVIDUAL CODIFICADO CON INFORMACION DEL SIMBOLO MEDIANTE LA UTILIZACION DE SEGMENTOS DEL SIMBOLO DEFINIDOS POR LOS EJES, AJUSTANDO EN PRIMER LUGAR A CADA SEGMENTO LA POSICION DEL EJE Y LAS DIMENSIONES DEL ELEMENTO PARA LA DETERMINACION POSTERIOR DE LA LOCALIZACION DE TODOS LOS ELEMENTOS QUE SE VANDECODIFICAR. SE PRESENTA EL SISTEMA COMO SI ESTUVIERA APLICADO A UN SIMBOLO CONSTRUIDO COMO UNA MATRIZ DE ELEMENTOS HEXAGONALES DE CODIFICACION DE INFORMACION COLOCADOS EN UN CUADRADO, QUE TIENE, EN SU CENTRO, UN OBJETIVO DE ADQUISICION QUE CONSISTE EN SEIS ANILLOS CONCENTRICOS DE LUZ ALTERNANTE Y REFLEXIVIDAD OSCURA. ADEMAS, SE PRESENTA UN METODO PARA COLOCAR UN OBJETIVO DE ADQUISICION QUE CONSISTE EN UNA PLURALIDAD DE ANILLOS CONCENTRICOS DE NIVELES ALTERNANTES DE REFLEXIVIDAD (MODELO OJOS DE TORO) EN SIMBOLOGIAS BIDIMENSIONALES. SE PUEDEN ENCONTRAR TALES OBJETIVOS INCLUSO SI VARIAN EN TAMAÑO Y EN ANGULO DE INCLINACION CON RESPECTO A LA CAMARA DE OBTENCION DE IMAGENES. LAS CARACTERISTICAS DE SIMETRIA DE LOS OBJETIVOS SE UTILIZAN PARA COLOCAR LOS OBJETIVOS INDEPENDIENTES DEL NIVEL DEL UMBRAL SELECCIONADO PARA DETERMINAR LAS TRANSICIONES ENTRE LOS ANILLOS DE DIFERENTE REFLEXIVIDAD.
