View-Dependent Dynamic Point Cloud Compression

Dynamic point cloud (DPC) captures 3D object and scene with realistic appearance to mimic the natural reality. It inherently offers the six-degree-of-freedom (6DoF) for content consumption, which motivates us to facilitate the network-friendly view-dependent DPC streaming by leveraging the limited f...

Abstract	Dynamic point cloud (DPC) captures 3D object and scene with realistic appearance to mimic the natural reality. It inherently offers the six-degree-of-freedom (6DoF) for content consumption, which motivates us to facilitate the network-friendly view-dependent DPC streaming by leveraging the limited field of view of the human visual system (HVS) at specific moments, for significant network bandwidth reduction without the quality of experience (QoE) loss. Therefore, in this work, we propose the view-dependent DPC compression, noted as View-PCC, by which we can enable instantaneous and complete view reconstruction from partial streams, and 6DoF navigation by stream adaptation. These functionalities are offered by the hybrid global and local projection to effectively map 3D points to five perpendicular 2D image planes of a cube. Multi-view and multi-layer based global projection is first applied progressively and followed by the patch-based local projection with both intra-frame displaced arrangement and inter-frame temporal alignment, so as to maximize the number of effectively projected points and preserve the spatio-temporal coherency for better compression. Boundary padding is then augmented for each image plane that will be encoded using the successful 2D video coding standard - High-Efficiency Video Coding (HEVC). Our extensive simulations have shown the noticeable objective compression gains of View-PCC when compared with the typical octree-based approach and global-projection-based method. The subjective quality assessment suggests the better reconstruction quality of View-PCC, in comparison to the MPEG video-based point cloud compression (V-PCC).
