Abstract

Un aparato para predecir un bloque predeterminado (18) de una imagen utilizando una pluralidad de muestras de referencia (17a,c). El aparato está configurado para formar (100) un vector de valores de muestras (102, 400) de la pluralidad de muestras de referencia, derivar a partir del vector de valores de muestras un vector adicional con el cual se mapea el vector de valores de muestras por medio de una transformación lineal invertible predeterminada, calcular un producto de vector de matriz entre el vector adicional y una matriz de predicción predeterminada para obtener un vector de predicción, y predecir muestras del bloque predeterminado con base en el vector de predicción.
