Abstract
(EN)
Compressing a frame of video includes receiving a frame of a video, identifying a three dimensional (3D) object in the frame, matching the 3D object to a stored 3D object, compressing the frame of the video using a color prediction scheme based on the 3D object and the stored 3D object, and storing the compressed frame with metadata, the metadata identifying the 3D object, indicating a position of the 3D object in the frame of the video and indicating an orientation of the 3D object in the frame of the video.
(FR)
La compression d'une trame de vidéo consiste à recevoir une trame d'une vidéo, identifier un objet tridimensionnel (3D) dans la trame, mettre en correspondance l'objet 3D avec un objet 3D stocké, compresser la trame de la vidéo à l'aide d'un schéma de prédiction de couleur sur la base de l'objet 3D et de l'objet 3D stocké, et stocker la trame compressée avec des métadonnées, les métadonnées identifiant l'objet 3D, indiquant une position de l'objet 3D dans la trame de la vidéo et indiquant une orientation de l'objet 3D dans la trame de la vidéo.
