Galaxy Image Restoration with Shape Constraint
Fadi Nammour, Morgan A. Schmitz, Fred Maurice Ngolè Mboula +2
Images acquired with a telescope are blurred and corrupted by noise. The blurring is usually modeled by a convolution with the Point Spread Function and the noise by Additive Gauss…

Euclid: Nonparametric point spread function field recovery through interpolation on a graph Laplacian
M. A. Schmitz, J. -L. Starck, F. Ngole Mboula +35
Context. Future weak lensing surveys, such as the Euclid mission, will attempt to measure the shapes of billions of galaxies in order to derive cosmological information. These surv…
