A practical preconditioner for wide-field continuum imaging of radio interferometric data
Hertzog L. Bester, Audrey Repetti, Simon Perkins +2
The celebrated CLEAN algorithm has been the cornerstone of deconvolution algorithms in radio interferometry almost since its conception in the 1970s. For all its faults, CLEAN is r…
Learning Maximally Monotone Operators for Image Recovery
Jean-Christophe Pesquet, Audrey Repetti, Matthieu Terris +1
We introduce a new paradigm for solving regularized variational problems. These are typically formulated to address ill-posed inverse problems encountered in signal and image proce…
The LOFAR Two Meter Sky Survey: Deep Fields, I -- Direction-dependent calibration and imaging
C. Tasse, T. Shimwell, M. J. Hardcastle +29
The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic surveys. It has a large field of view and is sensitive to large scale and compact emission. It…
Variable Metric Forward-Backward Algorithm for Composite Minimization Problems
Audrey Repetti, Yves Wiaux
We present a forward-backward-based algorithm to minimize a sum of a differentiable function and a nonsmooth function, both being possibly nonconvex. The main contribution of this…
Polca SARA - Full polarization, direction-dependent calibration and sparse imaging for radio interferometry
Jasleen Birdi, Audrey Repetti, Yves Wiaux
New generation of radio interferometers are envisaged to produce high quality, high dynamic range Stokes images of the observed sky from the corresponding under-sampled Fourier dom…
Compressive optical imaging with a photonic lantern
Debaditya Choudhury, Duncan K. McNicholl, Audrey RepettI +4
The thin and flexible nature of optical fibres often makes them the ideal technology to view biological processes in-vivo, but current microendoscopic approaches are limited in spa…
