Adaptive Geometry Partition for Point Cloud Compression

IEEE Transactions on Circuits and Systems for Video Technology, 2021
Octree (OT) geometry partitioning has been acknowledged as an efficient representation in state-of-the-art point cloud compression (PCC) schemes. In this work, an adaptive geometry partition and coding scheme is proposed to improve the OT based coding framework.

Implicit Geometry Partition for Point Cloud Compression

2020 Data Compression Conference (DCC), 2020
Octree (OT) geometry partitioning has been acknowledged as an efficient representation in state-of-the-art point cloud compression (PCC). In this work, a new geometry partition and coding scheme is proposed to improve the OT based coding framework, in which the quad-tree (QT) and binary-tree (BT) partitions are introduced.

Geometry compression of scanned point-clouds

2010 2nd International Conference on Software Technology and Engineering, 2010
Today, 3D scanners are capable of producing high resolution and accurate 3D computer models that are often used for entertainment, industrial, and scientific purposes. Because such models may contain a huge amount of points, their storage is expansive, their loading is slow, and their transmission over the internet is impossibly slow.

A Volumetric Approach to Point Cloud Compression–Part II: Geometry Compression

IEEE Transactions on Image Processing, 2020
Compression of point clouds has so far been confined to coding the positions of a discrete set of points in space and the attributes of those discrete points. We introduce an alternative approach based on volumetric functions, which are functions defined not just on a finite set of points, but throughout space.

Lossy Point Cloud Geometry Compression via Region-Wise Processing

IEEE Transactions on Circuits and Systems for Video Technology, 2021
Point cloud geometry (PCG) is used to precisely represent arbitrary-shaped 3D objects and scenes, is of great interest to vast applications which puts forward the pressing desire of high-efficiency PCG compression for transmission and storage. Existing PCG coding mostly relies on the octree model by which point-wise processing is applied without ...
