Abstract

This paper proposes a study about the introduction of lossy techniques over an intra-frame coder of the geometry information of voxelized point clouds (PC). Using an alternative representation approach, this method represents the PC as an array of binary images. Moreover, we sought to assess the quality of the decoded PC with different reconstruction techniques for a given bit rate. We observed that the use of the lossy proposed method alone wasn't enough to reach bitrates values below 0.2 bpov, which suggests the combination of this method with other lossy solutions in future studies.
