Abstract:
(EN) An intra-prediction mode-based image processing method, and an apparatus therefor are disclosed in the present invention. Specifically, the method for processing an image based on an intra-prediction mode may comprise the steps of: deriving an intra-prediction mode of a current block; generating at least one reference sample of a right, a lower and a lower right reference sample of a current block; generating a first prediction sample and a second prediction sample from reference samples neighbouring the current block based on the intra-prediction mode, wherein the neighbouring reference samples include at least one reference sample of a left, an upper, an upper left, a lower left, an upper right, a right, a lower and a lower right reference sample of the current block; and generating a final prediction sample using a weighted sum of the first prediction sample and the second prediction sample.
(FR) La présente invention concerne un procédé de traitement d'image basé sur un mode d'intra-prédiction et un dispositif associé. Plus particulièrement, le procédé de traitement d'une image basé sur un mode d'intra-prédiction peut comprendre les étapes consistant : à dériver un mode d'intra-prédiction d'un bloc actuel; à générer au moins un échantillon de référence d'un échantillon droit, inférieur et de référence droit inférieur d'un bloc actuel; à générer un premier échantillon de prédiction et un second échantillon de prédiction à partir d'échantillons de référence voisins du bloc actuel basés sur un mode d'intra-prédiction, les échantillons de référence voisins comprenant au moins un échantillon de référence d'un échantillon gauche, supérieur, gauche supérieur, gauche inférieur, droit supérieur, droit, inférieur et de référence droit inférieur du bloc actuel; et à générer un échantillon de prédiction final à l'aide d'une somme pondérée du premier échantillon de prédiction et du second échantillon de prédiction.
