Augmented Slepians: Bandlimited Functions that Counterbalance Energy in Selected Intervals
Robin Demesmaeker, Maria Giulia Preti, Dimitri Van De Ville
Slepian functions provide a solution to the optimization problem of joint time-frequency localization. Here, this concept is extended by using a generalized optimization criterion…
A Graph Signal Processing View on Functional Brain Imaging
Weiyu Huang, Thomas A. W. Bolton, John D. Medaglia +3
Modern neuroimaging techniques provide us with unique views on brain structure and function; i.e., how the brain is wired, and where and when activity takes place. Data acquired us…
Interpolation in the Presence of Domain Inhomogeneity
Hamid Behjat, Zafer Doğan, Dimitri Van De Ville +1
Standard interpolation techniques are implicitly based on the assumption that the signal lies on a homogeneous domain. In this letter, the proposed interpolation method instead exp…
When Slepian Meets Fiedler: Putting a Focus on the Graph Spectrum
Dimitri Van De Ville, Robin Demesmaeker, Maria Giulia Preti
The study of complex systems benefits from graph models and their analysis. In particular, the eigendecomposition of the graph Laplacian lets emerge properties of global organizati…
