Grid is Good: Adaptive Refinement Algorithms for Off-the-Grid Total Variation Minimization

Axel Flinth, Frédéric de Gournay, Pierre Weiss

We propose an adaptive refinement algorithm to solve total variation regularized measure optimization problems. The method iteratively constructs dyadic partitions of the unit cube…

Spurious minimizers in non uniform Fourier sampling optimization

Frédéric de Gournay, Alban Gossard, Pierre Weiss

A recent trend in the signal/image processing literature is the optimization of Fourier sampling schemes for specific datasets of signals. In this paper, we explain why choosing op…
