The Centre for Machine Vision in BRL is featured in Bang Goes the Theory on BBC 1 as part of a programme on 'Big Data' (Monday 24 March 2014).

Professor Melvyn Smith, Dr Mark Hansen and Laurence Broadbent were interviewed for the programme which will feature the Photoface work and 4D mapping systems.

The Centre for Machine Vision (CMV) is part of the Bristol Robotics Laboratory (BRL), a major research collaboration between the University of the West of England and the University of Bristol. It is one of only a handful of centres in the world exploring the application of photometric stereo.

The Centre aims to solve practical computer vision problems with direct application to the real world. The group's particular excellence lies in the sub-fields of three-dimensional reconstruction and surface inspection.

Bang Goes the Theory filmed the Photoface device invented by CMV which captures a 3D image of a person's face as they walk through it. The project has built a database of over 450 faces captured in 3,000 sessions using photometric stereo technology. The photometric stereo technology used in machine vision creates 3D and 4D images taken with light emitted from several different sources simultaneously in order to create deeper insights.

Director Professor Melvyn smith says, “We are really pleased to be able to show the cutting edge work of the Centre on this popular programme. It is a privilege to have the opportunity to explain our work to a wider audience, and to be able to share some of the insights from the research with the programme makers. The experience of working with the BBC has been excellent, and a useful learning exercise for the whole team.”

The Centre for Machine Vision (CMV)is taking a leading role in developing human-computer interaction technology for application in the real world.

Bang Goes the Theory can be viewed on the BBC iPlayer. The segment filmed at the BRL starts at 25.25.
