Keep the phase! Signal recovery in phase-only compressive sensing
Laurent Jacques, Thomas Feuillen
We demonstrate that a sparse signal can be estimated from the phase of complex random measurements, in a "phase-only compressive sensing" (PO-CS) scenario. With high probability an…
Going Below and Beyond, Off-the-Grid Velocity Estimation from 1-bit Radar Measurements
Gilles Monnoyer de Galland, Thomas Feuillen, Luc Vandendorpe +1
In this paper we propose to bridge the gap between using extremely low resolution 1-bit measurements and estimating targets' parameters, such as their velocities, that exist in a c…
When compressive learning fails: blame the decoder or the sketch?
Vincent Schellekens, Laurent Jacques
In compressive learning, a mixture model (a set of centroids or a Gaussian mixture) is learned from a sketch vector, that serves as a highly compressed representation of the datase…
One Bit to Rule Them All : Binarizing the Reconstruction in 1-bit Compressive Sensing
Thomas Feuillen, Mike Davies, Luc Vandendorpe +1
This work focuses on the reconstruction of sparse signals from their 1-bit measurements. The context is the one of 1-bit compressive sensing where the measurements amount to quanti…
MAYONNAISE: a morphological components analysis pipeline for circumstellar disks and exoplanets imaging in the near infrared
Benoît Pairet, Faustine Cantalloube, Laurent Jacques
Imaging circumstellar disks in the near-infrared provides unprecedented information about the formation and evolution of planetary systems. However, current post-processing techniq…
Factorization over interpolation: A fast continuous orthogonal matching pursuit
Gilles Monnoyer de Galland, Luc Vandendorpe, Laurent Jacques
We propose a fast greedy algorithm to compute sparse representations of signals from continuous dictionaries that are factorizable, i.e., with atoms that can be separated as a prod…
