CA 2404655

In video processing, a motion vector is identifed for each of a plurality of overlapping picture blocks. Pictures are then shifted in accordance with the motion vectors to provide multiple shifted pictures, and these are combined with weightings derived from the proximity of the associated pixel to the respective blocks.

Dans un procédé de traitement de signaux vidéo, on identifie un vecteur de mouvement pour chaque bloc faisant partie d'une pluralité de blocs d'images superposées. On décale les images en fonction des vecteurs de mouvement de manière à obtenir plusieurs images décalées, puis on combine ces dernières avec des pondérations dérivées de la proximité du pixel associé par rapport aux blocs respectifs.
