Fast Multiscale Diffusion on Graphs
Sibylle Marcotte, Amélie Barbe, Rémi Gribonval +4
Diffusing a graph signal at multiple scales requires computing the action of the exponential of several multiples of the Laplacian matrix. We tighten a bound on the approximation e…
Combining traffic counts and Bluetooth data for link-origin-destination matrix estimation in large urban networks: The Brisbane case study
Gabriel Michau, Nelly Pustelnik, Pierre Borgnat +3
Origin-Destination matrix estimation is a keystone for traffic representation and analysis. Traditionally estimated thanks to traffic counts, surveys and socio-economic models, rec…
Analytic signal in many dimensions
Mikhail Tsitsvero, Pierre Borgnat, Paulo Gonçalves
In this work we extend analytic signal theory to the multidimensional case when oscillations are observed in the orthogonal directions. First it is shown how to obtain separate…
Design of graph filters and filterbanks
Nicolas Tremblay, Paulo Gonçalves, Pierre Borgnat
Basic operations in graph signal processing consist in processing signals indexed on graphs either by filtering them, to extract specific part out of them, or by changing their dom…
