Edge-Adaptive Image ReconstructionCP3

Total variation and high order total variation methods for image reconstruction rely on sparsity throughout some domain. The spatial variation of the sparsity is not typically accounted for, however. We propose a new method for image reconstruction from non-uniform Fourier data that uses edge detection to indicate regions of sparsity and targets regularization appropriately.
