New research into public surveillance methods

12.07.2007
Research carried out by University of Southampton Masters students has identified the most effective ways of identifying individuals in public spaces.

In two separate research projects, two final year students of the MEng Master of Engineering Degree within the School of Electronics & Computer Science (ECS), Sarah Deane and Matthew Sharifi, who will graduate this month, addressed the growing importance of being able to identify individuals within a given environment, both from a security and marketing perspective.

Sarah’s project, A Comparison of Background Subtraction Techniques, highlighted the fact that most current Closed-Circuit Television (CCTV) footage fails to give a clear image of an object because it is often obscured by background information.

Having reviewed several existing methods for taking away the background information and not finding any of them particularly effective, Sarah used several of these theories, combining them into her own implementation.

‘I found that background subtraction, although being simply defined as a difference between the background image without objects of interest and an observed image, has many difficult issues to overcome,’ said Sarah. ‘It was apparent that a simple subtraction algorithm was needed to allow the high computational efficiency that is required by CCTV applications.’

Matthew’s project, Audience Recognition in Public Spaces compared the effectiveness of face recognition and Bluetooth as a means of recognising individuals within a public space.

He found that a camera positioned in a reception area was able to detect all of the frontal faces that came into contact with the system, whereas Bluetooth only managed to recognise 8.33% of those who passed and was dependant on these individuals carrying Bluetooth devices.

The results have inspired Matthew to conduct a much larger video dataset, so that he can carry out further experiments.

‘Having observed the advantages and disadvantages of both Bluetooth and face recognition, it would be interesting to combine the two techniques into a multi-modal identification technology which could couple the ubiquity of face recognition with the recognition accuracy of Bluetooth,’ he said.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
