Localized Iterative Methods for Interpolation in Graph Structured Data
Sunil K. Narang, Akshay Gadde, Eduard Sanou +1
In this paper, we present two localized graph filtering based methods for interpolating graph signals defined on the vertices of arbitrary graphs from only a partial set of samples…
Bilateral Filter: Graph Spectral Interpretation and Extensions
Akshay Gadde, Sunil K Narang, Antonio Ortega
In this paper we study the bilateral filter proposed by Tomasi and Manduchi, as a spectral domain transform defined on a weighted graph. The nodes of this graph represent the pixel…
Compact Support Biorthogonal Wavelet Filterbanks for Arbitrary Undirected Graphs
Sunil K. Narang, Antonio Ortega
In our recent work, we proposed the design of perfect reconstruction orthogonal wavelet filterbanks, called graph- QMF, for arbitrary undirected weighted graphs. In that formulatio…
The Emerging Field of Signal Processing on Graphs: Extending High-Dimensional Data Analysis to Networks and Other Irregular Domains
David I Shuman, Sunil K. Narang, Pascal Frossard +2
In applications such as social, energy, transportation, sensor, and neuronal networks, high-dimensional data naturally reside on the vertices of weighted graphs. The emerging field…
Perfect Reconstruction Two-Channel Wavelet Filter-Banks for Graph Structured Data
Sunil K. Narang, Antonio Ortega
In this work we propose the construction of two-channel wavelet filterbanks for analyzing functions defined on the vertices of any arbitrary finite weighted undirected graph. These…
