An Efficient LiDAR Point Cloud Map Coding Scheme Based on Segmentation and Frame-Inserting Network

open access: yesSensors, 2022
In this article, we present an efficient coding scheme for LiDAR point cloud maps. As a point cloud map consists of numerous single scans spliced together, by recording the time stamp and quaternion matrix of each scan during map building, we cast the ...

A Generic Scheme for Progressive Point Cloud Coding [PDF]

open access: yesIEEE Transactions on Visualization and Computer Graphics, 2008
In this paper, we propose a generic point cloud encoder that provides a unified framework for compressing different attributes of point samples corresponding to 3D objects with arbitrary topology. In the proposed scheme, the coding process is led by an iterative octree cell subdivision of the object space.

A Deep Point Cloud Geometry Coding Toolbox [PDF]

open access: yes2021 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2021
This short paper describes a TensorFlow toolbox for point cloud geometry coding based on deep neural networks. This coding method employs a deep auto-encoder trained with a focal loss to learn good representations for voxel occupancy. The software provides several coding parameters to achieve different rate-distortion trade-offs, and comes with pre ...

Performance Evaluation of the Codec Agnostic Approach in MPEG-I Video-Based Point Cloud Compression

open access: yesIEEE Access, 2021
In this study, we evaluated the codec agnostic approach of video-based point cloud compression (V-PCC) by applying several video codecs to V-PCC. The main concept of V-PCC is to use a video codec to compress the 2D patch images generated from a 3D point ...
