Abstract

Un método de codificación de acuerdo con una modalidad incluye una etapa de generación del índice y una etapa de codificación. La etapa de generación del índice genera un índice común en el cual, los números de una o más imágenes de referencia, incluidos en un primer índice son números de una o más imágenes de referencia incluidas en un segundo índice, se ordenan en una combinación para no incluir una misma imagen de referencia. El primer índice se establece para representar una combinación que incluye la una o más imágenes de referencia, referenciadas por una primera imagen de referencia. El segundo índice se establece para representar una combinación que incluye la una o más imágenes de referencia referenciadas por una segunda imagen de referencia. Los números de las imágenes de referencia incluidos en el primer índice y el segundo índice, se exploran en un orden predeterminado. La etapa de codificación codifica el índice común.
