Stable Phase Retrieval in Infinite Dimensions

Rima Alaifari, Ingrid Daubechies, Philipp Grohs +1

The problem of phase retrieval is to determine a signal $f \in H$ , with $H$ a Hilbert space, from intensity measurements $∣ F (ω) ∣$ , where $F(ω):=\langle f , φ_ω\r…

Cartoon Approximation with $α$ -Curvelets

Philipp Grohs, Sandra Keiper, Gitta Kutyniok +1

It is well-known that curvelets provide optimal approximations for so-called cartoon images which are defined as piecewise $C^{2}$ -functions, separated by a $C^{2}$ singularity curve.…

Intrinsic Localization of Anisotropic Frames II: $α$ -Molecules

Philipp Grohs, Stefano Vigogna

This article is a continuation of the recent paper [Grohs, Intrinsic localization of anisotropic frames, ACHA, 2013], where off-diagonal-decay properties (often referred to as 'loc…
