Title (EN) MOTION VECTOR PREDICTION USING PRIOR FRAME RESIDUAL
(FR) UTILISATION DE PRÉDICTION DE VECTEUR DE MOUVEMENT AVANT UN RÉSIDU DE TRAME
Abstract:
(EN) A mask is generated from a residual that is a difference between pixel values of at least two frames other than a current frame in a video sequence. The mask is then used to encode or decode a current block by inter-prediction. The mask forms an edge of an object within its bounds and can be used to combine different portions of a reference frame into a single block. This can increase coding efficiency.
(FR) Selon l'invention, un masque est généré à partir d'un résidu qui est une différence entre des valeurs de pixel d'au moins deux trames autres qu'une trame courante dans une séquence vidéo. Le masque est ensuite utilisé pour coder ou décoder un bloc courant par prédiction inter. Le masque forme un bord d'un objet dans ses limites et peut être utilisé pour combiner différentes parties d'une trame de référence en un seul bloc. Ceci peut augmenter l'efficacité de codage.
