    摘要: A method and device for encoding data representative of a 3D representation of a scene into a bitstream, the 3D representation being according to a range of points of view. To reach that aim, at least a depth map associated with at least a part of the 3D representation is generated according to at least a parameter representative of at least a two-dimensional parametrization associated with the at least a part and data associated with at least a point comprised in the at least a part, the at least a two-dimensional parametrization being responsive to geometric information associated with the at least a point and to pose information associated with the range of points of view. At least a texture map associated with the at least a part is generated according to the at least a parameter and data associated with the at least a point comprised in the at least a part. A first information representative of point density of points comprised in at least a part of the at least a part of the 3D representation is obtained. The at least a depth map is encoded into a first syntax element of the bitstream, the at least a texture map into a second syntax element of the bitstream, the at least a parameter into a third syntax element of the bitstream, the first information into a fourth syntax element of the bitstream and a second information representative of a mapping between the at least a two-dimensional parametrization and corresponding at least a depth map and at least a texture map into a fifth syntax element of the bitstream.
    Corresponding method and device for decoding the bitstream are also disclosed.

    摘要: The present invention provide a method, apparatus and system for reducing crosstalk of auto-stereoscopic displays using higher resolution panels. In such panels, a fraction of a total number of views is generated by sending a same signal on a number of adjacent views. A signal processing correcting function is applied to the fractioned views to reduce crosstalk.

    摘要: A method and device for modifying attributes of one or more points of a 3D scene, the attributes comprising depth attribute and texture attribute stored respectively in a depth image and a texture image. To reach that aim, at least a first point of the 3D scene is identified, the at least a first point having depth information inconsistent with regard to depth information associated with a neighborhood of the at least a first point in the depth image. It is then determined whether the attributes of the at least a first point are correctable by analyzing neighborhood of the at least a first point in the depth image and in the texture image. For each first point having correctable attributes, the attributes stored in the depth image and/or texture image are modified according to the neighborhood in the depth image and/or in the texture image.
