Subjective Quality Assessment of V-PCC-Compressed Dynamic Point Clouds Degraded by Packet Losses

open access: yesSensors, 2023
This article describes an empirical exploration on the effect of information loss affecting compressed representations of dynamic point clouds on the subjective quality of the reconstructed point clouds.

Joint Hybrid Backhaul and Access Links Design in Cloud-Radio Access Networks [PDF]

open access: yes, 2015
The cloud-radio access network (CRAN) is expected to be the core network architecture for next generation mobile radio systems. In this paper, we consider the downlink of a CRAN formed of one central processor (the cloud) and several base-station (BS ...

Performance Evaluation of Multiterminal Backhaul Compression for Cloud Radio Access Networks

open access: yes, 2013
In cloud radio access networks (C-RANs), the baseband processing of the available macro- or pico/femto-base stations (BSs) is migrated to control units, each of which manages a subset of BS antennas.

Point Cloud Compression with Implicit Neural Representations: A Unified Framework [PDF]

open access: yes2024 IEEE/CIC International Conference on Communications in China (ICCC)
Point clouds have become increasingly vital across various applications thanks to their ability to realistically depict 3D objects and scenes. Nevertheless, effectively compressing unstructured, high-precision point cloud data remains a significant ...

Example-based super-resolution for point-cloud video

open access: yes, 2018
We propose a mixed-resolution point-cloud representation and an example-based super-resolution framework, from which several processing tools can be derived, such as compression, denoising and error concealment. By inferring the high-frequency content of

Visual Quality of Compressed Mesh and Point Cloud Sequences

open access: yesIEEE Access, 2020
With the development of immersive video, the delivery and storage of 3D content have become important research areas. While compression methods for meshes and point clouds, the two main representations for 3D content, are actively studied, there are few ...

PIVOT-Net: Heterogeneous Point-Voxel-Tree-based Framework for Point Cloud Compression [PDF]

open access: yesInternational Conference on 3D Vision
The universality of the point cloud format enables many 3D applications, making the compression of point clouds a critical phase in practice. Sampled as discrete 3D points, a point cloud approximates 2D surface(s) embedded in 3D with a finite bit-depth ...

Point cloud compression based on hierarchical point clustering [PDF]

open access: yes2013 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference, 2013
In this work we propose an algorithm for compressing the geometry of a 3D point cloud (3D point-based model). The proposed algorithm is based on the hierarchical clustering of the points. Starting from the input model, it performs clustering to the points to generate a coarser approximation, or a coarser level of detail (LOD). Iterating this clustering

Fronthaul-Constrained Cloud Radio Access Networks: Insights and Challenges

open access: yes, 2015
As a promising paradigm for fifth generation (5G) wireless communication systems, cloud radio access networks (C-RANs) have been shown to reduce both capital and operating expenditures, as well as to provide high spectral efficiency (SE) and energy ...
