Abstract:
A decoding device for point cloud decoding includes a communication interface and a processor. The communication interface configured to receive a bitstream. The processor is configured to identify, from the bitstream, messages and one or more sub-bitstreams representing a three-dimensional (3D) point cloud. The processor is configured to identify a query label indicating an object of the 3D point cloud for decoding. In response to determining that the query label corresponds to a label, the processor is configured to identify a 3D scene object associated with the query label. The processor is configured to identify a 2D tile that correspond to the 3D scene object. The processor is configured to determine to decode, based on an identification of the 2D tile from the sub-bitstream, a portion of the sub-bitstream corresponding to the 2D tile to generate a portion of a video frame representing a portion of the 3D scene object.
