As any viewer of Crimewatch will know, E-fit pictures don’t always give a true likeness of a human face. However, all this is set to change thanks to researchers at the University of Kent who are working with their counterparts at the Open University to create a software system that will generate far more life-like, and therefore far more easily identifiable, faces.
Using a combination of computer science and forensic psychology, the team are developing a revolutionary system that will enable the user to create a face not by selecting physical features, such as skin tone or chin shape, but by selectively ‘breeding’ combinations of faces that exhibit similarity to the desired face. The system also allows the user to specify and modify a range of other attributes. This means it will be possible to show clearly whether someone looks more feminine or masculine or whether the person looked kind, mean, or even happy.
Dr Chris Solomon, the project leader, is a Senior Lecturer in the University’s School of Physical Sciences. He explains: ‘We have a tendency to see faces globally; we don’t remember them just as a collection of individual features. The use of these ‘semantic’ attributes enables people to interact with the system to create a face as they would actually have seen it. Part of the problem with current composite pictures is that they don’t really look human.’

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
