Claim 10:
11. A decoding device for point cloud decoding, the decoding device comprising:
a communication interface configured to receive a bitstream; and
a processor operably coupled to the communication interface, wherein the processor is configured to:
decode 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,
decode, 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,
reconstruct the 3D point cloud using the multiple frames and the occupancy map frame,
determine a format of the attribute frame, and
in response to a determination that the attribute frame is a YUV 420 format:
up scale the attribute frame to YUV 444 format, and
perform attribute smoothing to the 3D point cloud based on values associated with a zeroth component of the YUV 444 format.
