Continuous improvement of sound and image: Conference on the quality of multimedia experience

03.06.2013
Around 100 international researchers will convene at the Seepark Hotel Klagenfurt from July 3rd to 5th 2013, to attend the fifth international workshop on Quality of Multimedia Experience (QoMEX).

Amongst other things, they will explore how the quality experienced during the consumption of media can be made measurable. New technologies and products will be presented at the “QUALINET Industry Forum Expo”.

For some, the quality provided by a 20-year-old TV set is still perfectly adequate, while others express dissatisfaction with the grainy resolution of videos viewed on tablet PCs. “The range of perceptions of quality associated with the consumption of multimedia content are as varied as the people themselves”, workshop organiser Christian Timmerer reports. “In order to ensure that product innovations are tailored to consumer demands, we need methods of measurement”, he adds. Researchers across the globe are working on the calculation of quality metrics, which are based on subjective tests, but simultaneously permit objective assessments.

“Most differences only become apparent, when two levels of quality are placed side by side”, Timmerer explains. Conducting research in this field brings technicians very close to the realm of perceptual psychology and collaborations with experts from this field are frequent. In answer to the question whether film and TV, for example, might still offer room for quality improvement, even beyond HD and Ultra-HD, Timmerer shares his thoughts: “Many things are only visible to the trained eye. However, mankind is evolving alongside the media it produces, and people soon become accustomed to new standards.” He sees potential for improvement in relation to the achievable resolution, as well as in relation to the frame rate (image refresh rate). While, so far, 24 images are usually shown per second, some films featuring a high frame rate (HFR), show 48 images per second. Similarly, broader colour spaces can offer a more vivid experience of colour.
Timmerer and his colleagues at the Institute of Information Technology at the Alpen-Adria-Universität are also working on video effects involving additional light, air movement and vibration. “In this area, we are working to determine — as objectively as possible — how these effects are perceived and experienced by the viewers”, Timmerer reports.

QoMEX is the flagship scientific event co-sponsored by the European Network “COST Action IC1003 Qualinet” and the IEEE Signal Processing Society. After taking place in San Diego, CA, US (2009), Trondheim, NO (2010), Mechelen, BE (2011) and Yarra Valley, AU (2012), it will be hosted in Austria for the first time in 2013.

As part of the event, the “QUALINET Industry Forum” will take place on the 4th of July, providing representatives from the fields of science and industry with an opportunity to discuss innovations. Displayed in an exhibition setting, product innovations will be presented on site: These will include technologies, products and research results relating to the topics of High Dynamic Range (HDR), 3D Audio/Video (3DA/3DV) and Ultra High Definition (UHD).

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

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...

Im Focus: Climate satellite: Tracking methane with robust laser technology

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...

Im Focus: How protons move through a fuel cell

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...

Im Focus: A unique data centre for cosmological simulations

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...
