CA 2600410

A video coding and decoding method using a weighted prediction and an apparatus for the same are provided. The video coding method includes generating a predicted image for a present block; generating a weighted prediction factor which is a scaling factor of the predicted image that minimizes the difference between the present block and the predicted image; generating a weighted prediction image by multiplying the predicted image by the weighted prediction factor; and coding a residual signal generated by subtracting the weighted prediction image from the present block.

L'invention concerne un procédé de codage et de décodage vidéo utilisation une prédiction pondérée ainsi qu'un appareil afférent. Le procédé de codage vidéo consiste à générer une image prédite pour un bloc présent, à générer un facteur de prédiction pondéré lequel est un facteur d'échelle de l'image prédite réduisant au minimum la différence entre le bloc présent et l'image prédite, à générer une image de prédiction pondérée par multiplication de l'image prédite par le facteur de prédiction pondéré et à coder un signal résiduel généré par soustraction de l'image de prédiction pondérée du bloc présent.
