Topology-based Filtering of Graph Signals via Persistent Homology
Matias de Jong van Lier, Sebastián Elías Graiff Zurita, Shizuo Kaji
We study topology-based filtering of vertex-defined signals on graphs and their two-dimensional analogues. Unlike graph-spectral filters, the proposed approach distinguishes featur…
