Table 1. MRI datasets used in training, evaluation, and comparison to extant methods.
Methods employed include those proposed here (HippUnfold), the same processing but with manual segmentation (similar to previous work; DeKraker et al., 2020) (manual unfold), Freesurfer v7.2.0 (FS7) (Iglesias et al., 2015), and an atlas of manual segmentations (Berron et al., 2017) used in ASHS (Yushkevich et al., 2015b).
