M-Channel Critically Sampled Spectral Graph Filter Banks With Symmetric Structure
Akie Sakiyama, Kana Watanabe, Yuichi Tanaka
This paper proposes a class of -channel spectral graph filter banks with a symmetric structure, that is, the transform has sampling operations and spectral graph filters on both…

Eigendecomposition-Free Sampling Set Selection for Graph Signals
Akie Sakiyama, Yuichi Tanaka, Toshihisa Tanaka +1
This paper addresses the problem of selecting an optimal sampling set for signals on graphs. The proposed sampling set selection (SSS) is based on a localization operator that can…

Two-Channel Critically-Sampled Graph Filter Banks With Spectral Domain Sampling
Akie Sakiyama, Kana Watanabe, Yuichi Tanaka +1
We propose two-channel critically-sampled filter banks for signals on undirected graphs that utilize spectral domain sampling. Unlike conventional approaches based on vertex domain…
