  • Publication number: 20190228050
    Abstract: The systems and methods discussed herein implement a volumetric approach to point cloud representation, compression, decompression, communication, or any suitable combination thereof The volumetric approach can be used for both geometry and attribute compression and decompression, and both geometry and attributes can be represented by volumetric functions. To create a compressed representation of the geometry or attributes of a point cloud, a suitable set of volumetric functions are transformed, quantized, and entropy-coded. When decoded, the volumetric functions are sufficient to reconstruct the corresponding geometry or attributes of the point cloud.

  • Patent number: 10192353
    Abstract: A machine can be specially configured to generate, compress, decompress, store, access, communicate, or otherwise process a special data structure that represents a three-dimensional surface of an object. The data structure can be or include a pruned sparse voxel octree in which each node in the octree corresponds to a different block of the octree, and children of the node in the octree correspond to the smaller blocks that subdivide the block. Moreover, each block occupied by the surface or a portion thereof can define its enclosed surface or portion thereof explicitly or implicitly.

  • Publication number: 20180053324
    Abstract: A method for encoding a point cloud representing a scene using an encoder including a processor in communication with a memory includes steps of fitting a parameterized surface onto the point cloud having input points representing locations in a three-dimensional space, generating model parameters from the parameterized surface, computing corresponding points from the parameterized surface, wherein the corresponding points correspond to the input points, computing residual data based on the corresponding points and the input points of the point cloud, compressing the model parameters and residual data to yield coded model parameters and coded residual data, respectively, and producing a bit-stream from the coded model parameters of the parameterized surface and the coded residual data.
