MyWorld PhD Scholarship: Volumetric Video Compression Compression

About the Project

Among all video content, one of the areas that has grown significantly over recent years is based on the use of augmented and virtual reality (AR and VR) technologies. They have the potential for major growth, and developments in displays, interactive equipment, mobile networks, edge computing, and compression are likely to facilitate these in the coming years.

A key new format that underpins the development of these new technologies is referred to volumetric video, with commonly used formats including point clouds, multi-view + depth and equirectangular representations. Various volumetric video codecs have been developed to perform data compression for transmission or storage of these formats. To present/display volumetric video content, the compressed data is decoded and post-processed using synthesizer/renderer which enables 3DoF/6DoF viewing capabilities on AR or VR devices.

In this context, this 3.5 year PhD project will focus on the two essential stages within this workflow: volumetric video compression and post-processing. Inspired by recent advances in deep video compression and rendering, we will research novel AI-based production workflows for volumetric video content to significantly improve the coding efficiency and the perceptual quality of the final rendered content.

This project is funded by the MyWorld UKRI Strength in Places Programme at the University of Bristol. It fits well within one of the core research areas outlined in the MyWorld programme on video production and communications for immersive content. The student working on this project will gain experience on immersive video production workflows, from capture and contribution to live editorial production and delivery at scale to a growing variety of XR capable devices.
