Signal Analysis based on Complex Wavelet Signs
Martin Storath, Laurent Demaret, Peter Massopust
We propose a signal analysis tool based on the sign (or the phase) of complex wavelet coefficients, which we call a signature. The signature is defined as the fine-scale limit of t…

The L1-Potts functional for robust jump-sparse reconstruction
Andreas Weinmann, Martin Storath, Laurent Demaret
We investigate the non-smooth and non-convex -Potts functional in discrete and continuous time. We show -convergence of discrete -Potts functionals towards their conti…
