Table 1.
Mean directed Hausdorff distances for Baseline, Phys-Base, Aug, Strat, Phys-Strat, Phys-Aug, Strat-Aug, and Phys-Strat-Aug on segmentation task, across inference subjects. All Hausdorff distances are calculated against a Physics Gold Standard. Standard deviations quoted in brackets. Bold values represent statistically best performances.
