ADAPTIVE BLOCK PARTITIONING OF POINT CLOUDS FOR VIDEO-BASED COLOR COMPRESSION

Point cloud compression presents novel and challenging demands. Video-based solutions can harness existing video codec technology for efficient compression, however, the cloud's 3D geometry and attributes must be presented within a compatible, regular 2D grid. We propose a method for generating equally-sized, square-shaped video blocks containing point cloud color information. Our video blocks may be readily tiled into an image for efficient color compression through a traditional video codec. The focus is on the development of a computationally simple, voxel-to-image projection methodology. Results provide evidence of competitive performance, with average PSNR gains of 0.68dB and attribute (color) bitrate savings of -15.10%, with respect to MPEG’s G-PCC (TMC13 v5.1).
