Graph Variogram: A novel tool to measure spatial stationarity
Alexander Serrano, Benjamin Girault, Antonio Ortega
Irregularly sampling a spatially stationary random field does not yield a graph stationary signal in general. Based on this observation, we build a definition of graph stationarity…

Irregularity-Aware Graph Fourier Transforms
Benjamin Girault, Antonio Ortega, Shrikanth Narayanan
In this paper, we present a novel generalization of the graph Fourier transform (GFT). Our approach is based on separately considering the definitions of signal energy and signal v…
