Comparison of AIFPM and DPC under different simulation conditions. (A1–A2) PTFs of AIFPM and DPC. (B1–B4) Recovered phase maps using AIFPM and DPC under different illumination schemes without noise. (B5–B9) Recovered phase maps using DPC and AIFPM with different regularization parameters and updating step-sizes while adding same Gaussian white noise in their raw images. (C1–C9) The spectrums of the phase difference between (B1–B9) and the ideal input.
