Title
(EN) CONDITIONAL APPLICATION OF INTER PREDICTION WITH GEOMETRIC PARTITIONING IN VIDEO PROCESSING
(FR) APPLICATION CONDITIONNELLE DE LA PRÉDICTION INTER AVEC UN PARTITIONNEMENT GÉOMÉTRIQUE DANS LE TRAITEMENT VIDÉO
Abstract
(EN)
A method for processing a video includes performing a determination, by a processor, that a first video block is partitioned to include a first prediction portion that is non-rectangular and non-square; adding a first motion vector (MV) prediction candidate associated with the first prediction portion to a motion candidate list associated with the first video block, wherein the first MV prediction candidate is derived from a sub-block MV prediction candidate; and performing further processing of the first video block using the motion candidate list.
(FR)
L'invention concerne un procédé de traitement d'une vidéo consistant: à réaliser une détermination, par un processeur, selon laquelle un premier bloc vidéo est partitionné pour comprendre une première partie de prédiction qui est non rectangulaire et non carrée; à ajouter un premier candidat de prédiction de vecteur de mouvement (MV) associé à la première partie de prédiction à une liste de candidats de mouvement associée au premier bloc vidéo, le premier candidat de prédiction MV étant dérivé d'un candidat de prédiction MV de sous-bloc; et à effectuer un traitement supplémentaire du premier bloc vidéo à l'aide de la liste de candidats de mouvement.
