FACIAL RECOGNITION – HOW DOES IT WORK?

Facial recognition – how does it work? Liopa’s Chief Technology Officer Dr Fabian Campbell-West gives a brief introduction to the fascinating subject of facial recognition.

The technology, however, has been greatly advanced by Liopa specialists.

How?

Liopa’s research in the cutting-edge field of Visual Speech Recognition, and associated areas. has created three main applications for their products and expertise:-

  • Transforming Voice UI: Making everyday applications like virtual assistant, including Siri, Cortana and Alexa, in-vehicle voice control and smart home devices, ever better through improved accuracy. Liopa’s LipRead product uses visual reading and a proprietary machine learning approach for enhanced usability and quality.
  • Liveness Detection: LipSecure by Liopa brings real improvements to online and mobile User Authentication by confirming that a real person is present. Anti-spoofing technology asks a user to repeat an on-screen sequence of digits and is software-based for superb cost-effectivess.
  • Keyword Spotting: The power of the ability to identify occurrences of words/ phrases in video footage, bringing new capabilities to surveillance video analysis, broadcast monitoring and transcription.

The applications developed by Liopa, which combines the analysis of lip movements with AI-based technology, not only address the issue of background noise affecting voice recognition accuracy but take authentication to new levels. The products are the result of work at the Centre for Secure Information Technologies at Queen’s University Belfast.

The Liopa team includes proven expertise across commerce, software architectural design and development methodologies.
