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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
