Estimating hyperparameters and instrument parameters in regularized inversion. Illustration for SPIRE/Herschel map making
F. Orieux, J. -F. Giovannelli, T. Rodet +1
We describe regularized methods for image reconstruction and focus on the question of hyperparameter and instrument parameter estimation, i.e. unsupervised and myopic problems. We…
Image Reconstruction in Optical Interferometry
Éric Thiébaut, Jean-François Giovannelli
This tutorial paper describes the problem of image reconstruction from interferometric data with a particular focus on the specific problems encountered at optical (visible/IR) wav…
Data inversion for over-resolved spectral imaging in astronomy
T. Rodet, F. Orieux, J. -F. Giovannelli +1
We present an original method for reconstructing a three-dimensional object having two spatial dimensions and one spectral dimension from data provided by the infrared slit spectro…
