Comparison of the images reconstructed from the simulated data, demonstrating the convergence properties. (a) The ground truth of the amplitude and phase images. (b) The reconstructed images for low-dose simulations, and (c) those for high-dose simulations. The first and second rows show the amplitude and phase of the constructed images after 150 iterations, and the third and fourth rows show those after 300 iterations, for ePIE, rPIE and PINE. The insets show a magnified area. The black bars in the second row indicate 4 µm, and those in the insets are 0.5 µm. |
