The knowledge explosion, changing circumstances due to new forms of work and many technical developments determine that the knowledge acquired in education is not sufficient throughout life. Therefore, self-directed learning in the workplace is becoming increasingly important. This is a form of learning where a current information need is met …

Unlike textual document retrieval, searching of visual data is still far from satisfactory. There exist major gaps between the available solutions and practical needs in both accuracy and computational cost. This thesis aims at the development of robust and scalable solutions for visual search and retrieval. Specifically, we investigate two …

In the knowledge-based society, the maintenance and acquisition of new knowledge are vital for each individual. Changed living and working conditions and the rapid development of technology cause the half-life of knowledge to decrease. Therefore, the knowledge that is acquired in educational institutions is no longer sufficient for an entire …

3D tele-immersion (3DTI) has the potential of enabling virtual-reality-like interaction among remote people with real-time 3D video. However, today’s 3DTI systems still suffer from various performance issues, limiting their broader deployment, due to the enormous demand on temporal (computing) and spatial (networking) resources. Past research focused on system-centric approaches for …
