Distributed algorithm for graph signal inpainting

Siheng Chen, Aliaksei Sandryhaila, Jelena Kovacevic

ICASSP 2015accepted

We present a distributed and decentralized algorithm for graph signal inpainting. The previous work obtained a closed-form solution with matrix inversion. In this paper, we ease the computation by using a distributed algorithm, which solves graph signal inpainting by restricting each node to communi…

Sampling theory for graph signals

Siheng Chen, Aliaksei Sandryhaila, Jelena Kovacevic

ICASSP 2015accepted

We propose a sampling theory for finite-dimensional vectors with a generalized bandwidth restriction, which follows the same paradigm of the classical sampling theory. We use this general result to derive a sampling theorem for bandlimited graph signals in the framework of discrete signal processing…
