Abstract

En una modalidad, se propone un método para codificar un contenido de campo luminoso. El método es destacable en que comprende: - obtener, para una serie de rayos de luz (401) asociados con dicho contenido de campo luminoso, cuatro coordenadas por rayo de luz de una parametrización de dos planos (2000; 402, 403) de dicho contenido de campo luminoso; - obtener (2001), para cada rayo de luz de dicha serie, dos coordenadas de dichas cuatro coordenadas, correspondiendo a una proyección de dichos rayos de luz de dicha serie en un plano (404, 4058, P) perpendicular a los dos planos utilizados en dicha parametrización de dos planos, definiendo los puntos en un primer diagrama de rayos 2D ? (x1,x2), ?(y1, y2)); - aplicar (2002) una transformada de radón discreta en dicho primer diagrama de rayos 2D ? (x1,x2), ? (y1,y2) que entrega líneas de interés en dicho primer diagrama de rayos 2D; - codificar (2003) dichas líneas de interés en líneas codificadas de interés; y -almacenar (2004) dichas líneas codificadas de interés.
