Embedded Bit-Stream Region-of-Interest Coding of Point Cloud Attributes

This paper presents a novel approach to embedded Region-of-Interest (ROI) attribute coding for point clouds. The proposed method is an embedded point cloud attribute coder incorporating regions of interest. The method chosen was to interleave bit-streams for ROI and non-ROI regions, which brings us some advantages. Firstly, it is independent of any specific ROI detection algorithm. Secondly, no increased complexity is imposed on the decoder. The results demonstrate an improvement in the quality of reconstructed voxels within the ROI, accompanied by some degradation of reconstructed voxels outside the ROI.
