Neumann Networks for Inverse Problems in Imaging
Davis Gilton, Greg Ongie, Rebecca Willett
Many challenging image processing tasks can be described by an ill-posed linear inverse problem: deblurring, deconvolution, inpainting, compressed sensing, and superresolution all…

Super-resolution MRI Using Finite Rate of Innovation Curves
Greg Ongie, Mathews Jacob
We propose a two-stage algorithm for the super-resolution of MR images from their low-frequency k-space samples. In the first stage we estimate a resolution-independent mask whose…

Recovery of Piecewise Smooth Images from Few Fourier Samples
Greg Ongie, Mathews Jacob
We introduce a Prony-like method to recover a continuous domain 2-D piecewise smooth image from few of its Fourier samples. Assuming the discontinuity set of the image is localized…
