Thresholded Non-Uniform Fourier Frame-Based Reconstruction for Stripmap SAR
John McKay, Anne Gelb, Suren Jayasuriya +1
Fourier domain methods are fast algorithms for SAR imaging. They typically involve an interpolation in the frequency domain to re-grid non-uniform data so inverse fast Fourier tran…
Accelerated Variance Based Joint Sparsity Recovery of Images from Fourier Data
Theresa Scarnati, Anne Gelb
Several problems in imaging acquire multiple measurement vectors (MMVs) of Fourier samples for the same underlying scene. Image recovery techniques from MMVs aim to exploit the joi…
Total Variation Bayesian Learning via Synthesis
Victor Churchill, Anne Gelb
This paper presents a sparse Bayesian learning algorithm for inverse problems in signal and image processing with a total variation (TV) sparsity prior. Because of the prior used,…
High Order Edge Sensors with Regularization for Enhanced Discontinuous Galerkin Methods
Jan Glaubitz, Anne Gelb
This paper investigates the use of regularization for solving hyperbolic conservation laws based on high order discontinuous Galerkin (DG) approximations. We first use the…
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…
