Abstract

Una forma de realización ejemplificativa presenta un método para decodificar un grupo de elementos de imagen en un cuadro de una secuencia de video codificada. El método comprende determinar un modo de intrapredicción para el grupo de elementos de imagen y proveer una primera predicción del grupo de elementos de imagen de acuerdo con el modo de intrapredicción determinado. El método además comprende determinar un identificador de ubicación que individualiza una ubicación de una versión decodificada de otro grupo de elementos de imagen en un cuadro de la secuencia de video, y proveer una segunda predicción del grupo de elementos de imagen usando el identificador de ubicación determinado. Además, el método comprende identificar cuál subconjunto de una pluralidad de subconjuntos de modos de intrapredicción contiene el modo de intrapredicción determinado, donde cada subconjunto corresponde a una primera ponderación y una segunda ponderación asignadas a todos los modos de intrapredicción de ese subconjunto, y donde se asignan diferentes subconjuntos a diferentes primeras ponderaciones y diferentes segundas ponderaciones, y aplicar al menos una de la primera ponderación asignada al subconjunto identificado a la primera predicción con el objeto de generar una primera predicción ponderada y la segunda ponderación asignada al subconjunto identificado a la segunda predicción con el objeto de generar una segunda predicción ponderada. El método además comprende generar una versión decodificada del grupo de elementos de imagen usando una combinación de la primera predicción y la segunda predicción ponderada o una combinación de la primera predicción ponderada y la segunda predicción o usando una combinación de la primera predicción ponderada y la segunda predicción ponderada.
