Wavelets on Graphs via Spectral Graph Theory
David K Hammond, Pierre Vandergheynst, Rémi Gribonval
We propose a novel method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite weighted graph. Our approach is based on defining scaling…

Dequantizing Compressed Sensing: When Oversampling and Non-Gaussian Constraints Combine
Laurent Jacques, David K. Hammond, M. Jalal Fadili
In this paper we study the problem of recovering sparse or compressible signals from uniformly quantized measurements. We present a new class of convex optimization programs, or de…
