Lower jaw semi-automatic segmentation: A ground truth scheme (white) and an semi-automatic segmentation (GrowCut, gold) is shown, including an overlay for accuracy and accordance assessment of the open-source algorithm (GrowCut) and a superimposed visualization of the semi-automatic segmentation (gold) into a 3D visualization of the patient’s skull (gray).

<p>The upper jaw is faded out for a clear visualization. <i>Note</i>: <i>The segmented mandible is–due to missing teeth–strongly atrophied</i>. <i>The thin bone is well visualized by the semi-automatic algorithm (GrowCut)</i>. <i>Some semi-automatic inaccuracy can be observed at the mandible’s condyle</i>.
