Visual Computing and Multimedia

Overview

This research group comprises three labs, the Computational Geometry and Applications Lab (CGA Lab: Computational Geometry and Applications), the Multimedia Communications Lab, and the Multimedia Signal Processing and Security Lab (WaveLab, wavelab.at). 

Topics of research

Computational Geometry and Applications Lab:

  • computational geometry,
  • algorithms and data structures (particularly those with a geometric   flavor),
  • algorithm engineering,
  • program design, robustness and reliability,
  • GPU-based computing, and
  • applications of geometric algorithms and data structures in, e.g.,   computer-aided (geometric) design, computer-aided manufacturing,   geographical information systems,   computer graphics, visual computing, and virtual reality.

Multimedia Signal Processing and Security Lab:

  • multimedia security and biometrics,
  • medical image processing and analysis,
  • (wavelet-based) image and video compression,
  • visual object detection and tracking, and
  • visual data quality assessment.

    Geologists from the University of Salzburg are greatly benefiting from the recently concluded science agreement between Iran and Austria. At least three new cooperation projects are planned. The expertise of the Salzburg geologists in finding gold or rare earths is, for example, very much in demand in Iran. Rare earths are among the most coveted raw materials in the world.
    Thanks to a generous legacy by Kurt Zopf, the University of Salzburg awards the Kurt-Zopf Prize, which is endowed with 10,000 euros, for habilitated members of organizational units of the university, which cover the areas of humanities, cultural and / or social science, jurisprudence or theology.
    From now until 3 July, it is possible to register for the "ditact_women's IT summer school" of the University of Salzburg . It takes place from 21 August to 2 September at the Unipark Nonntal and at the Fachhochschule Salzburg: http://www.ditact.ac.at.
