Abstract

Un método para la decodificación de imágenes de acuerdo con la presente invención comprende: reconstruir un indicador del grupo de modos de predicción intra y un índice del modo de predicción del bloque actual; crear un primer grupo con los modos de predicción intra válidos de los bloques a la izquierda y arriba del bloque actual; y, del grupo indicado por el indicador del grupo de modos de predicción intra, seleccionar un modo de predicción intra correspondiente al índice del modo de predicción como el modo de predicción intra del bloque actual, en donde el tamaño del bloque de predicción está de acuerdo con la información relacionada con el tamaño de la transformación. por lo tanto, sobre la base de los modos de predicción intra de los bloque a la izquierda y arriba del bloque actual, el indicador del grupo de modos de predicción intra y el índice del modo de predicción se determinan al incluir en el grupo, los modos con probabilidad alta de ser idénticos al modo de predicción intra del bloque actual, reduciéndose por ello la cantidad de información de predicción intra a ser codificada.
