Spectral folding and two-channel filter-banks on arbitrary graphs
Eduardo Pavez, Benjamin Girault, Antonio Ortega +1
In the past decade, several multi-resolution representation theories for graph signals have been proposed. Bipartite filter-banks stand out as the most natural extension of time do…
CoronaSurveys: Using Surveys with Indirect Reporting to Estimate the Incidence and Evolution of Epidemics
Oluwasegun Ojo, Augusto García-Agundez, Benjamin Girault +22
The world is suffering from a pandemic called COVID-19, caused by the SARS-CoV-2 virus. National governments have problems evaluating the reach of the epidemic, due to having limit…
TILES-2018, a longitudinal physiologic and behavioral data set of hospital workers
Karel Mundnich, Brandon M. Booth, Michelle L'Hommedieu +11
We present a novel longitudinal multimodal corpus of physiological and behavioral data collected from direct clinical providers in a hospital workplace. We designed the study to in…
Region adaptive graph fourier transform for 3d point clouds
Eduardo Pavez, Benjamin Girault, Antonio Ortega +1
We introduce the Region Adaptive Graph Fourier Transform (RA-GFT) for compression of 3D point cloud attributes. The RA-GFT is a multiresolution transform, formed by combining spati…
Graph Vertex Sampling with Arbitrary Graph Signal Hilbert Spaces
Benjamin Girault, Antonio Ortega, Shrikanth S. Narayayan
Graph vertex sampling set selection aims at selecting a set of ver-tices of a graph such that the space of graph signals that can be reconstructed exactly from those samples alone…
