UWE and its partners have received £672,000 in funding for the three-year project from the Engineering and Physical Sciences Research Council's Fighting Crime programme.
Increased interest in biometric face recognition is timely because of concerns over terrorism. Likely applications include airport immigration control, crowd surveillance, controlling access to secure areas, ATMs and on-line accounts and mugshot identification. Other applications could be in the areas of forensic science, multimedia and communications.
UWE and Imperial College are recognised as two of only three UK centres with expertise in the technique, called photometric stereo, which uses subtleties in image shading to isolate and recover fine detail in 3D shapes.
Dr Smith said he was delighted to be working with the team from Imperial College, led by Professor Maria Petrou. He added, “As humans we have an amazing capacity to recognise faces. But automated face recognition is one of the most challenging research topics in the field of computer vision. The PhotoFace project aims to develop new forms of capturing 3D images of faces that allow them to be identified despite changes in pose, lighting or facial expression.”
The technique of photometric stereo was first described at the Massachusetts Institute of Technology (MIT) in the 1970s, but remained largely a laboratory curiosity until the early 1990s when a dynamic form was developed at UWE. This allowed moving surfaces with both 2D and 3D features to be analysed for the first time. The team at UWE have also been successful with other bids for funding for potential applications of the technique in fields such as medicine and industry as well as security.
Equipment for gathering data for the project, called PhotoFace, will be set up at UWE's Machine Vision Laboratory and at the South Wales Offices of General Dynamics UK Limited to collect data for this project.
Dr Melvyn Smith said, “Volunteers can walk through the unmanned device, which automatically detects their presence and scans their face as they walk through. They will be able to see a 3D relief of their face displayed as they exit the system.”
The project is being undertaken in collaboration with Imperial College, General Dynamics UK Limited, the Home Office (Scientific Development Branch) and Identity Solutions Ltd.
UWE's Machine Vision Laboratory is a member of the Bristol Vision Institute, a group which brings together members from a wide range of disciplines, from biological vision to artificial computer vision systems. The team at UWE consists of Dr Melvyn Smith, Centre Director and Reader in Machine Vision, Dr Lyndon Smith, Reader in Computer Simulation and Machine Vision, Dr Sagar Midha, Visiting Senior Research Fellow, Dr Abdul Farooq, Research Assistant, Dr Gary Atkinson Research Assistant, Dr Jiuai Sun Research Assistant and PhD students Kyle Zhou, Robin Ding and Raphael Wedowski.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
