Claim 15:
16. A method for point cloud decoding, the method comprising:
receiving a bitstream;
decoding the bitstream into multiple frames that include pixels, the multiple frames including an attribute frame, wherein a portion of the pixels are organized into patches and correspond to respective clusters of points of a three-dimensional (3D) point cloud;
decoding, from the bitstream, an occupancy map frame that indicates the portion of the pixels included in the multiple frames that represent the points of the 3D point cloud;
reconstructing the 3D point cloud using the multiple frames and the occupancy map frame;
determining a format of the attribute frame; and
in response to a determination that the attribute frame is a YUV 420 format:
up scaling the attribute frame to YUV 444 format, and
performing attribute smoothing to the 3D point cloud based on values associated with a zeroth component of the YUV 444 format.
