Image reconstruction from structured subsampled 2D Fourier data
Gerlind Plonka, Anahita Riahi
In this paper we study the performance of image reconstruction methods from incomplete samples of the 2D discrete Fourier transform. Inspired by requirements in parallel MRI, we fo…

Deterministic Sparse Sublinear FFT with Improved Numerical Stability
Gerlind Plonka, Therese von Wulffen
In this paper we extend the deterministic sublinear FFT algorithm in Plonka et al. (2018) for fast reconstruction of -sparse vectors of length , where we a…
