Best (top panels) and worst (bottom panels) cases based on the HD measure as obtained in the 3-D (A,C) and 2-D (B,D) pipelines (3-D best and worst cases: HD=3.37 mm, 17.6 mm; 2-D best and worst cases: HD=3.8 mm, 17.6 mm). In each panel (A-D), the ground truth (green) mesh overlaid with the predicted mesh (blue and red, for the 3-D and 2-D pipelines, respectively) are displayed on the left, while the HD mapped onto the ground truth mesh is displayed on the right.
