Nous envisageons la restauration d'observations en imagerie hyperspectrale de champs profonds de l'univers pour le projet instrumental MUSE. En raison de la taille massive des données et du fort niveau de bruit, le problème global de restauration demande à la fois une réduction de dimension et la prise en compte d'informations a priori...

September 2011 (v1)Conference paper
The study focuses on modelling and estimating the Point Spread Function of the hyperspectral data acquisition chain, for a ground-based instrument. The main difficulties lie in the PSF variations w.r.t. observational conditions, wavelength and position in the field of view. Such modelling is essential for the analysis and processing of these...
