Abstract

UN APARATO Y METODO PARA PROCESAR DATOS DE IMAGENES PARA DERIVAR BORDES Y SEGMENTOS DE LINEAS. LOS DATOS DE INTENSIDAD DE IMAGEN SON PROCESADOS EN UNA DIMENSION A LO LARGO DE UNAS SERIES DE LINEAS EXPLORADAS PARA PRODUCIR UNA CURVA DE INTENSIDAD (10). PARES DE PUNTOS A LO LARGO DE UNA CURVA DE LINEA EXPLORADA (10) QUE REPRESENTAN LA EXTREMA CURVATURA (20) SON CHEQUEADAS PARA DETERMINAR SI LA DIFERENCIA DE INTENSIDAD ENTRE LA EXTREMA CURVATURA (20) SON CARACTERISTICAS DE LOS BORDES. LOS PUNTOS DE LOS BORDES SON ENTONCES DETERMINADOS ENTRE LOS PARES DE EXTREMA CURVATURA. LOS PUNTOS DE LOS BORDES ENCONTRADOS ENTRE LA EXTREMA CURVATURA (20) SON ENTONCES CORRELACIONADOS CON OTROS PUNTOS DE BORDE EN PREVIAS LINEAS EXPLORADAS PARA DETERMINAR SI CAEN DENTRO DE UN RANGO DE SEGMENTOS DE LINEA PREDICHOS. LOS DATOS DE SEGMENTOS DE LINEA DEBEN ENTONCES SER PROCESADOS A NIVELES MAS ALTOS PARA IDENTIFICAR OBJETOS EN EL DATO.
