Project Description

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.
   

Privacy-protected Video Surveillance on Scalable Bitstreams (PrivSurv)

 

Project Description:

PrivSurv (FFG Bridge project 832082) is a project on developing privacy-protection mechanisms for video surveillance. Specific focus is set on applying RoI-based encryption technique on a bitstream basis, i.e. selectively encrypting JPEG2000 and H.264/SVC. This project is conducted in cooperation with Commend International GmbH and the Salzburg University of Applied Sciences (School of ITS).
