Abstract

EL RECONOCIMIENTO Y LA EVALUACION DE DEFECTOS DE COLOR LOCALMENTE LIMITADOS EN UNA CAPA SUPERFICIAL SELECTIVAMENTE REFLECTANTE SOBRE UNA HOJA DE VIDRIO SE REALIZA POR TRATAMIENTO DIGITAL DE DATOS DE UNA IMAGEN PROPORCIONADA POR UNA CAMARA DE VIDEO EN COLOR. CON EL ESTE FIN, LA HOJA DE VIDRIO REVESTIDA (1) SE ILUMINA MEDIANTE LUZ BLANCA Y LA LUZ REFLEJADA POR LA CAPA SUPERFICIAL (3) SE HACE VISIBLE SOBRE UNA PANTALLA DE PROYECCION (6). LA IMAGEN QUE APARECE SOBRE LA PANTALLA DE PROYECCION (6) ES DETECTADA POR UNA O VARIAS CAMARAS DE VIDEO EN COLOR (12, 13, 14, 15). PARA CADA UNA DE LOS TRES COLORES PRIMARIOS DE LA SUPERFICIE DETECTADA POR UNA CAMARA DE VIDEO EN COLOR, LA LUMINOSIDAD SE DETERMINA PARA CADA PUNTO DE IMAGEN. LA FRACCION DE COLOR RELATIVA SE DETERMINA POR DIVISION DE LOS VALORES DE LUMINOSIDAD DETERMINADA DE CADA COLOR PRIMARIO POR LA SUMA DE LOS VALORES DE LUMINOSIDAD DE LOS TRES COLORES PRIMARIOS EN EL NIVEL DE LOS PUNTOS DE IMAGEN CORRESPONDIENTES. LAS FRACCIONES DE COLOR RELATIVAS SE COMPARAN CON VALORES DE REFERENCIA PREDETERMINADOS.
