Richard Vigars

I received my M.Eng. in Electrical and Electronic Engineering from the University of Bristol in 2009, and my Ph.D., also from Bristol, in 2015. For my Ph.D. thesis, conducted under the supervision of Prof. David R. Bull, I developed a perceptual video codec that exploits prior knowledge of the structure of scenes in which the video is captured. A key theme of the research was combining understanding of the interactions scene geometry with the geometry of camera motion with understanding of the perceptually-redundant nature of texture under global or local motion.

For my postdoctoral research at Bristol, also under Prof. Bull, I applied my interest in the geometry of camera motion to address the efficiency of the mode decision algorithms of the H.265/HEVC video codec. This project included the development of a novel application of computer vision methods to analyse and improve the performance of contemporary video codecs.

Currently, I spend most of my time working at the Cardiff School of Art and Design’s Fovolab, working on mathematical models for perceptual nonlinear perspective.
