Abstract
(EN)
Apparatus for predicting a predetermined block (18) of a picture using a plurality of reference samples (17a, c) The apparatus is configured to form (100) a sample value vector (102, 400) out of the plurality of reference samples, derive from the sample value vector a further vector onto which the sample value vector is mapped by a predetermined invertible linear transform, compute a matrix-vector product between the further vector and a predetermined prediction matrix so as to obtain a prediction vector, and predict samples of the predetermined block on the basis of the prediction vector.

La présente invention concerne un appareil pour prédire un bloc prédéterminé (18) d'une image à l'aide d'une pluralité d'échantillons de référence (17a, c) l'appareil étant configuré pour former (100) un vecteur de valeur d'échantillon (102, 400) parmi la pluralité d'échantillons de référence, dériver, à partir du vecteur de valeur d'échantillon, un autre vecteur sur lequel le vecteur de valeur d'échantillon est mis en correspondance par une transformée linéaire inversible prédéterminée, calculer un produit de vecteur de matrice entre l'autre vecteur et une matrice de prédiction prédéterminée de façon à obtenir un vecteur de prédiction, et prédire des échantillons du bloc prédéterminé sur la base du vecteur de prédiction.
