Member Profile

This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Computer Sciences Department of the University of Salzburg headed by Andreas Uhl. The short name "WaveLab" already indicates that wavelets are among our favorite tools - we have 15 years of experience in this area. Our research is focused on Multimedia Security including Watermarking, Image and Video Compression, Medical Image Classification, and Biometrics.

Andreas Unterweger

 
 

About Me:
Andreas Unterweger was a Ph.D. student working on selective video encryption under the supervision of Prof. Uhl from January 2012 to February 2015. He is now a lecturer at the Salzburg University of Applied Sciences.

 
 

Research Interests:

  • Real-time video coding (especially H.264- and H.265-based video coding)
  • Selective video encryption
  • Image quality perception of the Human Visual System (HVS)
  • Video compression artifact assessment
