Figure 6

Example of masks that show poor dice coefficient, high HD, and MSD but with high accuracy in regions used for measuring metrics for diagnosing TAOD. Green outlines refer to AU-Net segmentation masks, white masks refer to ground truths. Blue lines refer to a visual depiction of how HD can be calculated. Red arrows refer to posterior ends of cranial bones with inaccurate posterior boundaries but are not used in determining TAOD metrics. Red circles refer to anterior ends that are used for determining TAOD metrics. (a) Basion masks. (b) Opisthion masks.
