Crime fighting potential for computerised lip-reading

21.02.2007
Researchers at the University of East Anglia are about to embark on an innovative new project to develop computer lip-reading systems that could be used for fighting crime.

The three-year project, which starts next month, will collect data for lip-reading and use it to create machines that automatically convert videos of lip-motions into text.

It builds on work already carried out at UEA to develop state-of-the-art speech reading systems.

The university is teaming up with the Centre for Vision, Speech & Signal Processing at Surrey University, who have built accurate and reliable face and lip trackers, and the Home Office Scientific Development Branch, who want to investigate the feasibility of using the technology for crime fighting.

The team also hope to carry out computerised lip-reading of other languages.

While it is known that humans can and do lip-read, not much is known about exactly what visual information is needed for effective lip-reading. Human lip-reading can be unreliable, even using trained lip-readers.

Dr Richard Harvey, senior lecturer at UEA’s School of Computing Sciences, is leading the project, which has been awarded £391,814 by the Engineering and Physical Sciences Research Council.

“We all lip read, for example in noisy situations like a bar or party, but even the performance of expert lip readers can be very poor,” he said.

“It appears that the best lip-readers are the ones who learned to speak a language before they lost their hearing and who have been taught lip-reading intensively. It is a very desirable skill.”

Dr Harvey added: “The Home Office Scientific Development Branch is interested in anything that helps the police gather information about criminals or gather evidence.”

As well as crime fighting there could be other potential uses for the technology, such as installing a camera in a mobile phone, or on the dash board for in-car speech recognition systems.

Another reason for developing computerised lip-reading is that the number of trained lip-readers is falling, mainly because people tend to be taught to sign instead.

Dr Harvey said: “To be effective the systems must accurately track the head over a variety of poses, extract numbers, or features, that describe the lips and then learn what features correspond to what text.

“To tackle the problem we will need to use information collected from audio speech. So this project will also investigate how to use the extensive information known about audio speech to recognise visual speech.

“The work will be highly experimental. We hope to have produced a system that will demonstrate the ability to lip-read in more general situations than we have done so far.”

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
