Abstract

SE PRESENTA UN SISTEMA PARA LOCALIZAR UN OBJETO POR LO MENOS DENTRO DE UNA IMAGEN DE INTENSIDAD. EL SISTEMA INCLUYE UN ELEMENTO (200) PARA ANALIZAR LA IMAGEN DE INTENSIDAD CON POR LO MENOS DOS DETECTORES DE BORDES DIFERENTES PARA DETECTAR UNA MULTIPLICIDAD DE BORDES ORIENTADOS EN POR LO MENOS DOS ALCANCES BIDIRECIONALES. HAY UN PRIMER ELEMENTO DE COMPARACION (300) PARA COMPARAR LA INFORMACION REPRESENTATIVA DE LOS BORDES DETECTADOS ANGULARMENTE ORIENTADOS EN UN PRIMER ALCANCE DIRECCIONAL Y LA INFORMACION REPRESENTATIVA DE LOS BORDES DETECTADOS ORIENTADOS ANGULARMENTE EN UN SEGUNDO ALCANCE DIRECCIONAL. TAMBIEN HAY ELEMENTOS (400) PARA SELECCIONAR UNA REGION DE PRIMER PLANO DE EN LA IMAGEN DE INTENSIDAD. LOS BORDES DETECTADOS EN LA REGION DE PRIMER PLANO SELECCIONADA SE ORIENTAN ANGULARMENTE SEGUN, SUSTANCIALMENTE, UNA ORIENTACION OBJETIVO.
