Thesis defense : Lucas Drumetz

Endmember variability in hyperspectral image unmixing place : Salle Mont-Blanc, GIPSA-lab, 11 Rue des Mathématiques, Saint Martin d’Hères. Abstract The fine spectral resolution of hyperspectral remote sensing images allows an accurate analysis of the imaged scene, but due to their limited spatial resolution, a pixel acquired by the sensor is…

Hassan Akbari: In this work, we use tensor decomposition methods in application of fetal ECG extraction from abdominal recordings. We propose a linear source separation algorithm based on a measure of quasi-periodicity. The quasi-periodicity is attained through the use of a constraint on both matrix factorization and tensor decomposition problems.…
