  • Publication number: 20230345016
    Abstract: Encoding efficiency for attribute information in point cloud information is improved. A point cloud encoding device includes a subsampling unit configured to preserve chroma signals of some points in a point cloud to be encoded and discard chroma signals of remaining points other than those points, and an attribute information encoding unit configured to encode the chroma signals of those points in the point cloud to be encoded and luma signals of all points.

  • Publication number: 20230342982
    Abstract: A point cloud coding device includes an interpolation unit configured to perform an interpolation process on a reconstructed point cloud of a coded frame with respect to attribute information in point cloud information and generating a reference frame of fractional precision, a motion estimation unit configured to perform motion estimation between the reference frame of fractional precision and the frame of integer precision to generate motion information, a prediction unit configured to generate a predicted value on the basis of the motion information, and an entropy coding unit configured to entropy-code the difference between a point cloud of the frame and the predicted value.
