Claim 0:
1. 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 whether to perform attribute smoothing to the 3D point cloud based at least in part on properties of the multiple frames, wherein the properties indicate an attribute type that is associated with at least one of the multiple frames and a quantity of components associated with the attribute type, and
perform the attribute smoothing to the 3D point cloud when:
the attribute type is Texture,
the quantity is one or three color components, and
a syntax element indicating that the attribute smoothing is enabled is identified from the bitstream.
