Detecting edges from non-uniform Fourier data via sparse Bayesian learning
Victor Churchill, Anne Gelb
In recent investigations, the problem of detecting edges given non-uniform Fourier data was reformulated as a sparse signal recovery problem with an l1-regularized least squares co…

Edge-adaptive l2 regularization image reconstruction from non-uniform Fourier data
Victor Churchill, Rick Archibald, Anne Gelb
Total variation regularization based on the l1 norm is ubiquitous in image reconstruction. However, the resulting reconstructions are not always as sparse in the edge domain as des…
