ROHSA: Regularized Optimization for Hyper-Spectral Analysis - Application to phase separation of 21 cm data
Antoine Marchal, Marc-Antoine Miville-Deschenes, Francois Orieux +5
Extracting the multiphase structure of the neutral interstellar medium (ISM) is key to understand the star formation in galaxies. The radiative condensation of the diffuse warm neu…
When does OMP achieve exact recovery with continuous dictionaries?
Clément Elvira, Rémi Gribonval, Charles Soussen +1
This paper presents new theoretical results on sparse recovery guarantees for a greedy algorithm, Orthogonal Matching Pursuit (OMP), in the context of continuous parametric diction…
Comparative study of image registration techniques for bladder video-endoscopy
Achraf Ben-Hamadou, Charles Soussen, Walter Blondel +2
Bladder cancer is widely spread in the world. Many adequate diagnosis techniques exist. Video-endoscopy remains the standard clinical procedure for visual exploration of the bladde…
Coherence-based Partial Exact Recovery Condition for OMP/OLS
Cedric Herzet, Charles Soussen, Jerome Idier +1
We address the exact recovery of the support of a k-sparse vector with Orthogonal Matching Pursuit (OMP) and Orthogonal Least Squares (OLS) in a noiseless setting. We consider the…
