Researchers use ‘complexity’ as a guiding tool to aid phase recovery for coherent X-ray imaging
Reconstruction from noisy diffraction data using RAAR-ER and CG-RAAR algorithms. (a) Ground-truth amplitude for the red blood cell (RBC) object (phase not shown). Simulated noisy oversampled Fourier intensity data of RBC in (a) corresponding to average light levels of (b) 1000 photons/pixel and (c) 500 photons/pixel. The data is displayed as |G|0.1 for display purposes. …
