*Dynamic Scene Reconstruction for Virtual Reality Video*

*Project Description*
The goal of this project is to reconstruct the geometry and appearance of
dynamic real-world environments to enable more immersive virtual reality
video experiences.

State-of-the-art VR video approaches (e.g. Anderson et al., 2016) produce
stereoscopic 360° video, which comprises separate 360° videos for the left
and right eye (like 3D movies, but in 360°). The videos can, for example,
be viewed on YouTube using a VR headset such as Google Cardboard or
Daydream. Unfortunately, such videos only allow viewers to look in
different directions, but they do not respond to any head motion such as
moving left/right, forward/backwards or up/down. Truly immersive VR video,
on the other hand, requires ‘freedom of motion’ in six degrees-of-freedom
(‘6-DoF’), so that viewers see the correct views of an environment
regardless of where they are (3 DoF) and where they are looking (+3 DoF).

This project aims to develop novel dynamic scene reconstruction techniques
that are capable of producing temporally-coherent, dense, textured,
time-varying 3D geometry from dynamic real-world environments from one or
more standard or 360-degree video cameras. In particular, the goal is to
convincingly reconstruct the visual dynamics of the real world, such as
people and moving animals or plants, so that the reconstructed dynamic
geometry can provide the foundation for a novel video-based rendering
approach that synthesises visually plausible novel views with 6
degrees-of-freedom for the specific head position and orientation of a
viewer in VR. This experience will provide correct motion parallax and
depth perception to the viewer (like Luo et al., 2018) to ensure
unparalleled realism and immersion.

Candidates should normally have a good first degree (equivalent to a First
Class or 2:1 Honours), or a Master’s degree in computer science, visual
computing or a related discipline. A strong mathematical background and
strong previous programming experience, preferably in C++ and/or Python, is
required. Candidates must have a strong interest in visual computing, and
previous experience in computer vision, computer graphics and image
processing is highly desirable.

Informal enquiries should be directed to Dr Christian Richardt,

Formal applications should be made via the University of Bath’s online
application form for a PhD in Computer Science:

*Funding Notes*
UK and EU students applying for this project may be considered for a
University Research Studentship which will cover Home/EU tuition fees, a
training support fee of £1,000 per annum and a tax-free maintenance
allowance at the RCUK Doctoral Stipend rate (£14,777 in 2018-19) for a
period of 3.5 years.

Note: ONLY UK and EU applicants are eligible for this studentship;
unfortunately, applicants who are classed as Overseas for fee-paying
purposes are NOT eligible for funding.
