The dual approach to non-negative super-resolution: impact on primal reconstruction accuracy
Stephane Chretien, Andrew Thompson, Bogdan Toader
We study the problem of super-resolution, where we recover the locations and weights of non-negative point sources from a few samples of their convolution with a Gaussian kernel. I…

Sparse non-negative super-resolution -- simplified and stabilised
Armin Eftekhari, Jared Tanner, Andrew Thompson +2
The convolution of a discrete measure, , with a local window function, , is a common model for a measurement device whose resolution is substantia…
