摘要： A system may include a demultiplexer, atlas component decoder, and an atlas pre-processing subsystem that includes a processor, and a non-transitory computer readable medium having encoded thereon a set of instructions executable by the processor to arrange one or more sub-bitstreams of a decoded atlas bitstream into one or more blocks, assign head information to each block, and generate a block-order decoded atlas bitstream, wherein generating the block-order decoded atlas bitstream includes ordering the one or more blocks of the decoded atlas bitstream in a scan order following a space-filling curve.

摘要： A method for decoding three-dimensional (3D) content comprising extracting a video frame from a video, wherein the video frame includes connectivity information associated with the 3D content; and reconstructing the 3D content based on the connectivity information. The reconstructing comprises: determining an end of the connectivity information with respect to a mesh frameblock based on a termination connectivity coding unit (CCU) in the block; and determining an end of the connectivity information with respect to a mesh frame based on a termination block in the mesh frame.

摘要： Systems and methods of the present disclosure provide solutions that address technological challenges related to 3D content. These solutions include a computer-implemented method for encoding three-dimensional (3D) content comprising: determining connectivity information of a mesh frame; packing the connectivity information of the mesh frame into coding blocks; dividing the coding blocks into connectivity coding units (CCUs) comprising connectivity coding samples; and encoding a video connectivity frame associated with the mesh frame based on the coding blocks and the connectivity coding units.
