(a) Structural similarity indices (SSIMs) between ground truth and various reconstructed images from noiseless data. The reconstructed phase contrast images were compared against the highpass filtered phase image shown in Fig. 6(d). (b) Euclidian distance error $d_{\text{affine}}$ (Eq. (6)) for the recovered affine transformation matrix ${\mathit{A}}_r$, under different choices for loss function and regularizer, and different fluences $\overline{n}$.
