A priori par normes mixtes pour les problèmes inverses Application à la localisation de sources en M/EEG (original) (raw)

We are interested by under-determined inverse problems, and more specifically by source localization in magneto and electro- encephalography (M/EEG). In these problems, despite we have a physical model of diffusion (or "mixing") of the sources, the (very) under- determined aspect of the problem leads to a very diffucult inversion. The need of finding strong and physically relevant prior on the
