Groupe de travail "Images" 

Ressources Images

Pour permettre de tester les méthodes développées, une banque d'images a été constituée.

Elle est disponible en accès restreint, aux partenaires du projet. Certaines images astronomiques ne sont pas publiques.
A titre indicatif, voici une liste des lots disponibles.
