Research Report: Exact biconvex reformulation of the $ℓ_{2} - ℓ_{0}$ minimization problem

Arne Bechensteen, Laure Blanc-Féraud, Gilles Aubert

We focus on the minimization of the least square loss function either under a $k$ -sparse constraint or with a sparse penalty term. Based on recent results, we reformulate the $\ell…

Single molecule localization by $ℓ_{2} - ℓ_{0}$ constrained optimization

Arne Bechensteen, Laure Blanc-Féraud, Gilles Aubert

Single Molecule Localization Microscopy (SMLM) enables the acquisition of high-resolution images by alternating between activation of a sparse subset of fluorescent molecules prese…
