Abstract
Se proporciona un sistema que es utilizable en un sistema de procesamiento para decodificación de una secuencia que incluye una pluralidad de imágenes, en donde el grupo de imágenes incluye una imagen de anclaje que sirve como una referencia para codificar toda la pluralidad de imágenes y al menos una imagen de referencia que sirve como una referencia para codificar al menos algunas de las otras del grupo de imágenes, la pluralidad de imágenes definida en una pluralidad de capas jerárquicas de acuerdo el orden de codificación. La codificación incluye codificar un l-esímo subconjunto de la pluralidad de imágenes de la primera capa jerárquica de acuerdo con una complejidad de imagen de la l-esíma capa jerárquica, y después de codificar el l-esímo conjunto de la pluralidad de imágenes de la l-esíma capa jerárquica, codificar un l-esímo + 1 [mutuamente exclusivo] subconjunto de la pluralidad de imágenes de una l-esímo + 1 capa jerárquica de acuerdo con una segunda medición de complejidad de imagen de capa jerárquica.
