Query: Refining the bounding volumes for lossless compression of voxelized
  point clouds geometry   This paper describes a novel lossless compression method for point cloud
geometry, building on a recent lossy compression method that aimed at
reconstructing only the bounding volume of a point cloud. The proposed scheme
starts by partially reconstructing the geometry from the two depthmaps
associated to a single projection direction. The partial reconstruction
obtained from the depthmaps is completed to a full reconstruction of the point
cloud by sweeping section by section along one direction and encoding the
points which were not contained in the two depthmaps. The main ingredient is a
list-based encoding of the inner points (situated inside the feasible regions)
by a novel arithmetic three dimensional context coding procedure that
efficiently utilizes rotational invariances present in the input data.
State-of-the-art bits-per-voxel results are obtained on benchmark datasets.
