Project Description

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.
   

Towards more reliability and less invasiveness in celiac disease diagnosis: Computer-aided detection and assessment of affected mucosa in endoscopic videos (CeliacVideo)

 

Project Description:

CeliacVideo (FWF KLI project 429) is a joint project led by Andreas Vecsei from the St. Anna Children's Hospital in Vienna, where we have the role of a national research partner. Celiac disease (CD) has a prevalence of 1%. To confirm the diagnosis, in children with serologically suspected CD until recently small bowel biopsy was recommended. To avoid biopsies but still reliably prove the diagnosis, a variety of new endoscopic techniques including software for the analysis of endoscopic still images has been developed. If automated analysis-software can detect villous atrophy not only in endoscopic still images but in video clips as well, in such cases, a small bowel biopsy could entirely be avoided. The main question we will try to assess is, if such software can be developed and easily integrated into the routine of pediatric endoscopy. Furthermore, we will examine if the narrow band imaging technique, an optical/digital chromoendoscopy, can further improve the reliability of automated analysis. Various feature extraction and classification strategies will be applied for automated differentiation between presence and absence of villous atrophy in the endoscopic video clips.
