Sampling and Reconstruction of Sparse Signals on Circulant Graphs - An Introduction to Graph-FRI
Madeleine S. Kotzagiannidis, Pier Luigi Dragotti
With the objective of employing graphs toward a more generalized theory of signal processing, we present a novel sampling framework for (wavelet-)sparse signals defined on circulan…

Splines and Wavelets on Circulant Graphs
Madeleine S. Kotzagiannidis, Pier Luigi Dragotti
We present novel families of wavelets and associated filterbanks for the analysis and representation of functions defined on circulant graphs. In this work, we leverage the inheren…
