Successive Nonnegative Projection Algorithm for Linear Quadratic Mixtures
Christophe Kervazo, Nicolas Gillis, Nicolas Dobigeon
In this work, we tackle the problem of hyperspectral (HS) unmixing by departing from the usual linear model and focusing on a Linear-Quadratic (LQ) one. The proposed algorithm, ref…

Heuristics for Efficient Sparse Blind Source Separation
Christophe Kervazo, Jerome Bobin, Cecile Chenot
Sparse Blind Source Separation (sparse BSS) is a key method to analyze multichannel data in fields ranging from medical imaging to astrophysics. However, since it relies on seeking…
