Journal ArticleDOI
On the decomposition of Mars hyperspectral data by ICA and Bayesian positive source separation
Saïd Moussaoui,Hafrun Hauksdottir,Frédéric Schmidt,Christian Jutten,Jocelyn Chanussot,David Brie,Sylvain Douté,Jon Atli Benediktsson +7 more
TL;DR: A combination of spatial ICA with spectral Bayesian positive source (BPSS) with a rough classification of pixels is proposed, which allows selection of small, but relevant, number of pixels for the component extraction and consequently the endmember classification.
Journal ArticleDOI

TL;DR: The observed changes in H2O and HDO abundance occurred within a few days during the development of the dust storm, suggesting a fast impact of dust storms on the Martian atmosphere.
Journal ArticleDOI
Climatic control of sediment transport from the Himalayas to the proximal NE Bengal Fan during the last glacial-interglacial cycle
Ronan Joussain,Ronan Joussain,Christophe Colin,Zhifei Liu,Laure Meynadier,Léa Fournier,Kelly Fauquembergue,Sébastien Zaragosi,Frédéric Schmidt,Virginia Rojas,Franck Bassinot +10 more
TL;DR: In this paper, the authors used deep-sea sediments cored in the north-eastern Bay of Bengal are used to reconstruct evolution of detrital sources and sediment transport to the proximal part of the Bengal deepsea fan during the last climatic cycle.
Journal ArticleDOI
Implementation Strategies for Hyperspectral Unmixing Using Bayesian Source Separation
Frédéric Schmidt,Albrecht Schmidt,Erwan Treguier,Mael Guiheneuf,Saïd Moussaoui,Nicolas Dobigeon +5 more
TL;DR: In this paper, the effects of pixel selection and the impact of sampling on the relevance of the estimated component spectra and abundance maps, as well as on the computation times are discussed.
Journal ArticleDOI
Formation of recurring slope lineae on Mars by rarefied gas-triggered granular flows.
Frédéric Schmidt,F. Andrieu,François Costard,Miroslav Kocifaj,Miroslav Kocifaj,Alina G. Meresescu +5 more
TL;DR: In this paper, the authors present numerical simulations to demonstrate that such a dry process involving the pumping of rarefied gas in the Martian soil due to temperature contrasts can explain the formation of the recurring slope lineae.
