Abstract
Systems and methods are disclosed herein for temporally predictive coding of three-dimensional (3D) dynamic point cloud attributes. A first frame and a second frame of point cloud data are accessed. The point cloud data points include 3D spatial coordinates and one or more graphic attributes. A block tree data structure comprising a plurality of blocks is generated based on a tree partitioning of the second frame of point cloud data. Matching block pairs between the first frame and the second frame are identified from the plurality of blocks based on block-wise searching. Frequency-domain projections are generated for each matching block pair via a graph Fourier transform (GFT) algorithm. A bitstream of motion-compensated residuals is generated based on differences in the frequency-domain projections for each matching block pair.
