Ongoing Research Projects in Biomedical Signal Processing - Some Results and many Challenges
Jean-Marc Vesin, EPFL

Seminar • 10 January 2008 • BM 5.202

Abstract
Biomedical signal processing relies more and more on advanced techniques for data pre-processing (notably interference cancellation) and clinically-relevant feature extraction. The current state of several projects in our group will be introduced. Our investigation of the mechanisms of cardiac atrial fibrillation (AF) will be presented in some detail, especially the central role of the computer model of AF that we have developed. Characterization of the gastro-intestinal tract activity using an innovative device ("magnet tracing") will be presented, and some time given to our work on the analysis of EEG and in-depth brain electrode signals. A recurrent theme in all these projects being the tracking of time-varying frequency components, the last part of the talk will be devoted to developments we pursue in this domain.
