Abstract

LAS SEÑALES Y OBJETOS DESCONOCIDOS SE LEEN OPTO - ELECTRONICAMENTE Y LAS SEÑALES DE LECTURA SE DIGITALIZAN PARA IDENTIFICACION DE UNA REPRODUCCION BINARIA DE LA SEÑAL Y OBJETO QUE SE COMPARA CON LAS IMAGENES DE TRAMA DE REFERENCIA BINARIAS ALMACENADAS EN EL ALMACEN DE REFERENCIA DE SEÑALES Y OBJETOS TEORICOS CONOCIDOS, CON LO QUE LA O LAS IMAGENES DE TRAMA DE REFERENCIA, QUE TIENEN LA MAYOR COINCIDENCIA CON LAS SEÑALES U OBJETOS LEIDOS, SE SELECCIONAN PARA IDENTIFICACION DE LAS SEÑALES U OBJETOS INTRODUCIDOS. LAS IMAGENES DE TRAMA DE REFERENCIA BINARIAS DEL ALMACEN FORMAN UN PRIMER PLANO DE COMPARACION BINARIO. SE PREVE AL MENOS OTRO PLANO DE COMPARACION BINARIO, QUE SE FORMA POR IMAGENES DE TRAMA DE REFERENCIA, QUE SE PRODUCE POR REPRODUCCION BINARIA DE MARCAS O PARTES CARACTERISTICAS DE LAS SEÑALES Y OBJETOS CONOCIDOS. LA SEÑAL U OBJETO EFECTIVO INTRODUCIDO Y FORMADO BINARIAMENTE SE COMPARA AL MENOS CON UNA IMAGEN DE TRAMA DE REFERENCIA DE OTRO PLANO DE COMPARACION SOBRE COINCIDENCIA, SILA COMPARACION CON LA IMAGEN DE DE TRAMA DE REFERENCIA DEL PRIMER PLANO DE COMPARACION O EL PRIMER PLANO DE COMPARACION EN COMBINACION CON OTRO PLANO DE COMPARACION PRODUCE UN GRADO DE COINCIDENCIA SITUADO POR DEBAJO DE UN VALOR UMBRAL PREDETERMINADO.
