Sub-aperture SAR Imaging with Uncertainty Quantification
Victor Churchill, Anne Gelb
In the problem of spotlight mode airborne synthetic aperture radar (SAR) image formation, it is well-known that data collected over a wide azimuthal angle violate the isotropic sca…
Image reconstruction enhancement via masked regularization
Victor Churchill, Anne Gelb
Image reconstruction based on an edge-sparsity assumption has become popular in recent years. Many methods of this type are capable of reconstructing nearly perfect edge-sparse ima…
Edge-masked CT image reconstruction from limited data
Victor Churchill, Anne Gelb
This paper presents an iterative inversion algorithm for computed tomography image reconstruction that performs well in terms of accuracy and speed using limited data. The computat…
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…
