Abstract

Un método y una disposición para insertar imágenes en campos de televisión en vivo incluye un método para identificar rápida y eficientemente marcas yobjetos. Inicialmente, se pasa una primer plantilla, que tiene una primera configuración similar a una de las características distintivas del objeto,sobre el campo de video y se compara con el mismo para identificar en forma preliminar por los menos una característica distintiva posible como candidato.Luego se crea una segunda plantilla tomando uno de los elementos fundamentales de la característica distintiva en potencia y extendiendo ese elementocompletamente a través de la segunda plantilla y luego comparándola con la característica distintiva en potencia. Esto elimina uno omás característicasposibles falsamente identificadas. A continuación se crea una tercera plantilla que tiene una configuración formada por otro elemento importante de dichacaracterística distintiva y se extiende totalmente a través de la terceraplantilla. Luego la tercera plantilla se pasa igualmente sobre lacaracterística distintiva candidato y se compara con la misma para eliminar otras posibles características falsamente identificadas. El método se continúahasta que se hayan eliminado todas las posibles falsas alarmas. El proceso se repite una vez más para identificar en forma preliminar dos o tres marcasdistintivas del objeto buscado. Las posiciones de esos objetos se comparan con un modelo geométrico para verificar adicionalmente si el objeto ha sidocorrectamente identificado. La metodología puede ser comprobada contra un programa grabado en video para determinar si identifica correctamente losobjetos.
