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.
   

Computer-assisted evaluation of endoscopic pictures of the duodenal mucosa of children with positive celiac serology (EndoCeliac)

 

Project Description:

EndoCeliac (Austrian National Bank Jubiläumsfonds project no. 12991 by the St. Anna Children's Hospital Vienna) is a joint project with Andreas Vecsei from the St. Anna Children's Hospital in Vienna. The aim of the project is to develop a computer-based decision support system for an automated diagnosis of celiac disease based on endoscopic colon imagery. Staging is done according to the Marsh calssification scheme. Images are acquired at the St. Anna Children's Hospital in Vienna and are transfered to Salzburg in anonymous fashion. The histological classification is available as ground truth. The Salzburg branch is developing custom classification techniques based on various features extracted from the spatial, Fourier-type, and Wavelet-type domains where the aim is to achieve at least equivalent classification results as compared to the histological findings.
