EPSRC Press Release
Live TV outside broadcasts that combine real action and computer-generated images could become possible for the first time, thanks to camera navigation technology now under development. The work is opening up the prospect of outdoor sporting, musical or other TV coverage that blends the excitement of being live with the spectacular visual impact that computer graphics can create. It can also be applied at the consumer level, e.g. to enable interior design ideas to be visualised by adding virtual furniture to the view of a room provided by a hand-held camera as it moves.
The system is able to work out in real-time where a camera is and how it is moving, simultaneously constructing a detailed visual map of its surroundings. This enables computer graphics to be overlaid accurately onto live pictures as soon as they are produced. Previously the blending of live action and computer-generated images has only been possible in controlled studio environments.

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
The oceans are the largest global heat reservoir. As a result of man-made global warming, the temperature in the global climate system increases; around 90% of...
