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.


This code implements the Embedded Multiresolution Mixture Models (EMMs), as proposed by Vasconcelos, N. and Lippman, A. We provide MATLAB files for fitting EMMs and similarity measurement by using the Feature Likelihood as well as two approximations to the Kullback-Leibler divergence between multivariate Gaussian mixture models. The tarball includes a PDF file documenting the implementation of the algorithms and further lists additional references.
