This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Artificial Intelligence and Human Interfaces (AIHI)
Department of the University of Salzburg led by Andreas Uhl.
Our research is focused on Visual Data Processing and associated security questions. Most of our work is currently concentrated on Biometrics, Media Forensics and
Media Security, Medical Image and Video Analysis, and application oriented fundamental research in digital humanities, individualised aquaculture and sustainable wood
industry.
Note to Reviewers: Software and data related to a publication will be published on this site only after the related paper has been accepted.
Keywords:nice,leg,lfbvs,ssim,psnr,lss,ess,im,vqi, image metric, visual quality index
Comment: Simple implementation of a small number of visual quality indices. The implementation aims at preventing image file type hassle rather than fast runtime.
Comment: The PLUSVein-Contactless Finger and Hand Vein Database was acquired with our two custom designed combined fully contact-less finger and hand vein acquisition device.
Comment: This database contains images with recognition scores, obsever score which are the basis for the recognition scores are also contained within.
