Abstract

UN SISTEMA PARA DETECTAR UN OBJETO EN UNA ESCENA. LA INVENCION (10) CONSTA DE UNA MEMORIA (12) PARA ALMACENAR UNA PRIMERA MEMORIA DE DATOS DE IMAGENES REPRESENTADA POR UNA PLURALIDAD DE SEÑALES DE ENTRADA IO. HAY UN FILTRO ESPACIAL (16) PARA FILTRAR ESPACIALMENTE UNA SEGUNDA MEMORIA DE DATOS DE IMAGENES REPRESENTADA POR UNA PLURALIDAD DE SEÑALES DE ENTRADA IO PARA PROPORCIONAR UNAS PRIMERAS SEÑALES DE SALIDA DEL FILTRO ESPACIAL A MODO DE NSIO. SE SUSTRAEN ESTAS SEÑALES DE LA PRIMERA MEMORIA DE DATOS DE IMAGENES PARA OBTENER LAS SEÑALES DE DIFERENCIA DEL MODO NDLO, DONDE ND REPRESENTA UNA MEDIDA DE REGISTRO DEL OBJETO. HAY UN SEGUNDO FILTRO ESPACIAL (18) PARA FILTRAR ESPACIALMENTE LAS SEÑALES DE DIFERENCIA PARA PROPORCIONAR LAS SEÑALES DE DIFERENCIA FILTRADAS ESPACIALMENTE A MODO DE NSNDIO. FINALMENTE, SE PROCESAN LAS SEÑALES (30) PARA EXTRAER LA MEDIDA DE REGISTRO DEL OBJETO ND.
