Abstract[English]
An electronic device and method for adaptive mode selection for point cloud compression, is provided. The electronic device receives a 3D point cloud geometry and partitions the 3D point cloud geometry into a set of 3D blocks. For a 3D block of the set of 3D blocks, mode decision information is determined. The mode decision information includes class information of the 3D point cloud geometry, operational conditions associated with an encoding stage of the 3D point cloud geometry, or mode-related information associated with one or more 3D blocks of the set of 3D blocks. Based on the mode decision information, one or more modes are selected for the 3D block from a plurality of modes. Each mode corresponds to a function that is used to encode the 3D block. The 3D block is encoded based on the one or more modes.[French]
L'invention concerne un dispositif électronique et un procédé de sélection de mode adaptatif permettant la compression de nuage de points. Le dispositif électronique reçoit une géométrie de nuage de points 3D et partitionne la géométrie de nuage de points 3D en un ensemble de blocs 3D. Pour un bloc 3D de l'ensemble de blocs 3D, des informations de décision de mode sont déterminées. Les informations de décision de mode comprennent des informations de classe de la géométrie de nuage de points 3D, des conditions de fonctionnement associées à un étage de codage de la géométrie de nuage de points 3D, ou des informations relatives au mode associées à un ou à plusieurs blocs 3D de l'ensemble de blocs 3D. Sur la base des informations de décision de mode, un ou plusieurs modes sont sélectionnés pour le bloc 3D parmi une pluralité de modes. Chaque mode correspond à une fonction qui est utilisée pour coder le bloc 3D. Le bloc 3D est codé sur la base du ou des modes.
