Registration accuracy of method variations as (a) volume overlap D using the Dice metric, and (b) mean symmetric surface distance S between label contours. Each box shows mean accuracy over anatomical structures for 50 test-image pairs across distinct subjects (8 for PD). The letters b and x indicate skull-stripping and registration across datasets (e.g. OASIS-HCP), respectively. Arrows indicate values off the chart.
