Multi-channel Sampling on Graphs and Its Relationship to Graph Filter Banks

2022 · arXiv (Cornell University)

In this paper, we consider multi-channel sampling (MCS) for graph signals. We generally encounter full-band graph signals beyond the bandlimited one in many applications, such as piecewise constant/smooth and union of bandlimited graph signals. Full-band …

Constructing an Interpretable Deep Denoiser by Unrolling Graph Laplacian Regularizer

2024 · arXiv (Cornell University)

An image denoiser can be used for a wide range of restoration problems via the Plug-and-Play (PnP) architecture. In this paper, we propose a general framework to build an interpretable graph-based deep denoiser (GDD) by …
