A method and system (102) for encoding a video stream using a compact representation for rotations and normals (200). The method and system (102) convert rotations and normals (200) into normalized rotations and normals and then project the normalized versions onto a unit cube (215). Each rotation and normal (200) is encoded according to on which face it was projected. In addition, motion can be compactly represented by movement across the unit cube (215).

L'invention concerne un procédé et un système de codage d'un train vidéo au moyen d'une représentation compacte pour les rotations et les perpendiculaires. Le procédé et le système de l'invention permettent la conversion des rotations et des perpendiculaires en rotations perpendiculaires normalisées, et de projeter les versions normalisées sur un cube unité. Chaque rotation et perpendiculaire est codée en fonction de la face sur laquelle elle est projetée. Par ailleurs, le mouvement peut être représenté de manière compacte par un mouvement dans le cube unité.
