Spectral map**s for graph wavelets

DB Tay - IEEE Transactions on Signal Processing, 2022 - ieeexplore.ieee.org
Graph wavelet filters can be used to construct dictionaries of atoms, and signals defined
over graphs can be represented as linear combinations of these atoms. These …

Filter design for two-channel filter banks on directed bipartite graphs

DB Tay - IEEE Signal Processing Letters, 2020 - ieeexplore.ieee.org
Graph signal processing on directed graphs is more challenging that on undirected graph,
primarily because the graph matrices, eg, adjacency or Laplacian, associated with the latter …

M-channel graph filter banks: Polyphase analysis and structures

DB Tay, A Ortega - IEEE Signal Processing Letters, 2019 - ieeexplore.ieee.org
Two channel critically sampled filter banks for signal over graph domains were first
proposed for undirected bipartite graphs by Narang and Ortega. Extension to the M-channel …

Sampling Theory for Graph Signals With Applications to Semi-Supervised Learning

A Anis - 2017 - search.proquest.com
The representation, processing and analysis of large-scale data as signals defined over
graphs has drawn much interest recently. Graphs allow us to embed natural inter …
