Close Encounters of the Binary Kind: Signal Reconstruction Guarantees for Compressive Hadamard Sampling with Haar Wavelet Basis
Amirafshar Moshtaghpour, José M. Bioucas Dias, Laurent Jacques
We investigate the problems of 1-D and 2-D signal recovery from subsampled Hadamard measurements using Haar wavelet sparsity prior. These problems are of interest in, e.g., computa…

One-Bit Sensing of Low-Rank and Bisparse Matrices
Simon Foucart, Laurent Jacques
This note studies the worst-case recovery error of low-rank and bisparse matrices as a function of the number of one-bit measurements used to acquire them. First, by way of the con…
