Spectrum-Adapted Tight Graph Wavelet and Vertex-Frequency Frames
David I Shuman, Christoph Wiesmeyr, Nicki Holighaus +1
We consider the problem of designing spectral graph filters for the construction of dictionaries of atoms that can be used to efficiently represent signals residing on weighted gra…

Structure of nonstationary Gabor frames and their dual systems
Nicki Holighaus
We investigate the structural properties of dual systems for nonstationary Gabor frames. In particular, we prove that some inverse nonstationary Gabor frame operators admit a Walnu…
