Figure 2
Comparison of deep learning based post-processing performance on reconstructed images from the simulated foam phantom dataset (Pelt et al., 2022 ) affected by local artifacts (noise) and non-local artifacts. The red and green insets show enlarged views of the affected areas. Peak signal to noise ratio (PSNR) and structural similarity index measure (SSIM) (Wang et al., 2004 ) values are provided in the top-right and lower-right corners, respectively. Deep learning based post-processing is less effective in reducing global artifacts than noise. While this figure demonstrates differences in artifact reduction based on simulation, similar challenging scenarios can occur in real-world dynamic experiments (Bührer et al., 2019 ) or fast scan setups (Raufaste et al., 2015 ; Mokso et al., 2017 ) at synchrotron facilities. |
