Research Interests

Parallel Algorithms for Multimedia Applications in Embedded Systems
Parallel architectures have become a driving force in recent years, addressing problems from high performance to low energy consumption. This is due to the fact that monocores cannot efficiently take usage of the ever increasing number of transistors per chip, whereas system-on-a-chip with several cores become feasible. It can be shown that these systems outperform monocores. This transition is even happening in embedded systems, where additional constraints arise like limited memory and bus bandwidth as well as battery runtime. Hence, algorithms have to be found which are especially geared towards these systems and which take care of the above mentioned issues.

3D Display Systems
Recent years have seen the introducing of a manifold of different 3D displays to the market. However, most displays still suffer from issues like crosstalk and visual artifacts. Furthermore, content generation for these system does not consist of simply generating two different pictures, many other aspects have to be taken into account as well. These are all reasons which hinder the growth of the 3D display market, thus solutions addressing these shortcomings have to be found.
