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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
