Robust microphone array signal processing against diffuse noise
We consider the general problem of microphone array signal processing in diffuse noise environments. This has various applications epitomized by speech enhancement and... -
Restauration d'images biologiques 3D en microscopie confocale par Transformée...
La microscopie confocale est une méthode puissante pour l'imagerie 3D de spécimens biologiques. Néanmoins, les images acquises sont dégradées non seulement par du flou... -
