Abstract

La presente solicitud se refiere a un decodificador y codificador y sus métodos relativos a codificar y decodificar un grupo de elementos de imagen en un cuadro de una secuencia de video codificado. El método comprende: proveer una primera producción del grupo de elementos de imagen de acuerdo con un modo de primera predicción; proveer una segunda predicción del grupo de elementos de imagen de acuerdo con un modo de segunda predicción; modificar la segunda predicción en respuesta al contenido de frecuencia de la misma para generar una segunda predicción modificada; y generar una versión decodificada del grupo de elementos de imagen usando una combinación de la primera predicción y la segunda predicción modificada.
