  • Hybrid geometric coding of point clouds
    Patent number: 12175715
    Abstract: An apparatus comprises a processor configured to obtain a point cloud, make a choice between octree encoding or quadtree encoding of a parent node, and encode the parent node into a bitstream based on the choice; and a transmitter coupled to the processor and configured to transmit the bitstream. An apparatus comprises a receiver configured to receive a bitstream; and a processor coupled to the receiver and configured to parse from the bitstream a first parameter indicating a depth of PCC, decode first nodes before the depth using octree decoding, parse from the bitstream a second parameter indicating a node coding mode for second nodes at and after the depth, and decode the second nodes based on the second parameter.

  • Method and apparatus for adaptive point cloud attribute coding
    Patent number: 11606561
    Abstract: A method of adaptive point cloud attribute coding is performed by at least one processor and includes determining a centroid of k candidate points of a point cloud, k being a predetermined sampling rate of all points of the point cloud, and selecting one of the k candidate points that is closest to the centroid. The method further includes determining a first levels-of-detail (LoD) layer comprising the one of the k candidate points, and a second LoD layer without the one of the k candidate points, and performing coding of attributes of the all points, based on the first LoD layer and the second LoD layer.
