London, Sept 14 (ANI): A sophisticated new camera system that can detect lies just by watching our faces as we talk has been unveiled at the British Science Festival in Bradford.
The computerised system uses a simple video camera, a high-resolution thermal imaging sensor and a suite of algorithms, the BBC reported.
Researchers say the system, developed by a team from the universities of Bradford and Aberystwyth in conjunction with the UK Border Agency, could be a powerful aid to security services.
It successfully discriminates between truth and lies in about two-thirds of cases, said lead researcher Professor Hassan Ugail from Bradford University.
We give our emotions away in our eye movements, dilated pupils, biting or pressing together our lips, wrinkling our noses, breathing heavily, swallowing, blinking and facial asymmetry. And these are just the visible signs seen by the camera.
Even swelling blood vessels around our eyes betray us, and the thermal sensor spots them too.
"We bring together all this well-established work on expressions, these recent developments in thermal imaging, techniques for image tracking of subjects and our new algorithms into one operational system," said Professor Ugail. (ANI)
