Abstract

Un sistema de inserción coloca eficientemente imágenes estáticas o dinámicas en una transmisión en vivo de video. El sistema identificainicialmente los hitos naturales dentro de la escena de video que pueden identificarse y seguirse automáticamente a medida que el campo visual de lacámara recorre y se acerca a la escena. Las ubicaciones de los hitos están matemáticamente modeladas y almacenadas como una constelación en una rejillamatemática. Un punto de referencia arbitrio,preferiblemente no necesariamente coincidente con un hito natural seleccionado, está ubicado dentro o fuera de larejilla y se usa como un origen para el fin de insertar la imagen estática o dinámica dentro del campo visual de la cámara. Para imágenes estáticas, esfrecuentemente deseable colocar un margen o borde de la imagen a insertarse en el punto de referencia. Para inserciones dinámicas, la distancia entre elpunto de referencia y la imagen dinámica insertada se cambia automáticamente demarco a marco para hacer que la imagen aparezca como si se estuvieratrasladando o cambiando o ambas.
