A Generic Scheme for Progressive Point Cloud Coding
A Generic Scheme for Progressive Point CloudCodingYan Huang,Jingliang Peng, Jay KuoandM. GopiAbstract In this paper, we propose a Generic Point cloudencoder that provides a unified framework for compressingdifferent attributes of Point samples corresponding to 3D objectswith arbitrary topology. In the proposed Scheme , the codingprocess is led by an iterative octree cell subdivision of theobject space. At each level of subdivision, positions of pointsamples are approximated by the geometry centers of all tree-front cells while normals and colors are approximated by theirstatistical average within each of tree-front cells. With thisframework, we employ attribute-dependent encoding techniquesto exploit different characteristics of various attributes. All ofthese have led to significant improvement in the rate-distortion(R-D) performance and a computational advantage over thestate of the art.
