Innovative models and algorithms for astronomical imagingMS9

The next generation of astronomical imaging instruments provides the chance for an unprecedented step forward in our knowledge of how the universe evolved. It also poses incredible challenges due to the huge amount of data to be processed and the need for a precise and self-consistent analysis of images with widely different depths and resolutions. Defining new approaches to restore, segment and analyse such images is both a fundamental and a challenging task. By combining experiences from two different fields, astrophysics and mathematics, this minisymposium aims at creating an interdisciplinary bridge that can be an enrichment for both research areas.
