Abstract:
A decoding device, method, and computer readable medium for partial access metadata for video-based point cloud compression data are disclosed. The decoding device for point cloud decoding includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives a compressed bitstream and metadata related to the compressed bitstream. The processor identifies, in the metadata, region information that indicates a region of a point cloud based on a user perspective; locates a track of the compressed bitstream that corresponds to the region information; identifies, in the track, objects corresponding to the region of the point cloud; and decodes for display of an object, included in the objects identified in the track, that is visible from the user perspective.
