Abstract
Al menos una modalidad se refiere a un método para rellenar una primera imagen de profundidad representativa de valores de profundidad de puntos más cercanos de un cuadro de nube de puntos y una segunda imagen de profundidad representativa de valores de profundidad de puntos más alejados de un cuadro de nube de puntos. El método también comprende codificar una corriente de video incluyendo una intercalación en tiempo de dichas primera y segunda imágenes codificadas. También se proporciona un método que comprende decodificar una corriente de video para proporcionar una primera imagen de profundidad representativa de valores de profundidad de puntos más cercanos de un cuadro de nube de puntos y una segunda imagen de profundidad representativa de valores de profundidad de puntos más alejados de un cuadro de nube de puntos, y filtrar valores de pixel de la segunda imagen de profundidad utilizando valores de pixel de la primera imagen de profundidad.
