Abstract

Aparato para decodificar un bloque predeterminado (18) de una imagen usando intrapredicción, configurado para leer, del flujo de datos (12), un índice de modo (200), el índice de modo que apunta a uno de una lista (204) de modos de intrapredicción basada en matriz. Además, el aparato se configura para predecir muestras (108) del bloque predeterminado (18) al calcular un producto de matriz-vector (206) entre un vector de entrada (102) derivado de muestras de referencia (17) en un entorno del bloque predeterminado (18) y una matriz de predicción (19) asociada con el modo de intrapredicción basada en matriz (k) apuntado por el índice de modo (200) y asociar componentes (210) de un vector de salida (208) obtenido por el producto de matriz-vector (206) en posiciones de muestra (104) del bloque predeterminado. Para cada modo de intrapredicción basada en matriz, todas las entradas de la matriz de predicción (19) asociada con el modo de intrapredicción basada en matriz respectivo se representan por una representación de punto fijo de una profundidad de bits predeterminada, la profundidad de bits predeterminada que es igual para los modos de intrapredicción basada en matriz. Además, el aparato se configura para, para cada modo de intrapredicción basada en matriz, calcular el producto de matriz-vector (206) entre el vector de entrada (102) y la matriz de predicción (19) asociada con el modo de intrapredicción basada en matriz (k) respectivo al realizar, para cada componente del vector de salida, un desplazamiento hacia la derecha en un número de bits que es igual para los modos de intrapredicción basada en matriz.
