Abstract: front page image
(EN)Method of transforming a voxel representation of an N-dimensional object into a computer model containing a cellular space, which is a specific form of graph. An indicator attached to each edge of the cellular space indicates whether a border belongs to an object. This is useful for three-dimensional compression of video sequences and for Internet video sequence search.
(FR)L'invention concerne un procédé de transformation d'une représentation voxel d'un objet N-dimensionnel en un modèle informatique contenant un espace cellulaire qui est une forme spécifique de graphique. Un indicateur fixé à chaque bord de l'espace cellulaire indique si une limite appartient à l'objet. Ceci s'avère utile pour une compression tridimensionnelle de séquences vidéo et pour une recherche de séquences vidéo par Internet.
