SLS (Single Selection): a new greedy algorithm with an -norm selection rule
Ramzi Ben Mhenni, Sébastien Bourguignon, Jérôme Idier
In this paper, we propose a new greedy algorithm for sparse approximation, called SLS for Single L_1 Selection. SLS essentially consists of a greedy forward strategy, where the sel…
Some detection tests for low complexity data models and unknown background distribution
D. Mary, S. Bourguignon, E. Roquain +2
We consider several detection situations where, under the alternative hypothesis, the signal admits a low complexity model and, under both the null and the alternative hypotheses,…
Efficiency of BRDF sampling and bias on the average photometric behavior
Frederic Schmidt, Sebastien Bourguignon
The Hapke model has been widely used to describe the photometrical behavior of planetary surface through the Bi-directional Reflectance Distribution Function (BRDF), but the uncert…
Joint reconstruction strategy for structured illumination microscopy with unknown illuminations
Simon Labouesse, Awoke Negash, Jérôme Idier +5
The blind structured illumination microscopy (SIM) strategy proposed in (Mudry et al., 1992) is fully re-founded in this paper, unveiling the central role of the sparsity of the il…
Blind fluorescence structured illumination microscopy: A new reconstruction strategy
S. Labouesse, M. Allain, J. Idier +4
In this communication, a fast reconstruction algorithm is proposed for fluorescence \textit{blind} structured illumination microscopy (SIM) under the sample positivity constraint.…
On the super-resolution capacity of imagers using unknown speckle illuminations
Jérôme Idier, Simon Labouesse, Marc Allain +3
Speckle based imaging consists of forming a super-resolved reconstruction of an unknown sample from low-resolution images obtained under random inhomogeneous illuminations (speckle…
A Bayesian approach to the modelling of alpha Cen A
M. Bazot, S. Bourguignon, J. Christensen-Dalsgaard
Determining the physical characteristics of a star is an inverse problem consisting in estimating the parameters of models for the stellar structure and evolution, knowing certain…
