An algorithm for variable density sampling with block-constrained acquisition
Claire Boyer, Pierre Weiss, Jérémie Bigot
Reducing acquisition time is of fundamental importance in various imaging modalities. The concept of variable density sampling provides a nice framework to achieve this. It was jus…
Geodesic PCA in the Wasserstein space
Jérémie Bigot, Raúl Gouet, Thierry Klein +1
We introduce the method of Geodesic Principal Component Analysis (GPCA) on the space of probability measures on the line, with finite second moment, endowed with the Wasserstein me…
An analysis of block sampling strategies in compressed sensing
Jérémie Bigot, Claire Boyer, Pierre Weiss
Compressed sensing is a theory which guarantees the exact recovery of sparse signals from a small number of linear projections. The sampling schemes suggested by current compressed…
