Median qualitative segmentation results for the hippocampus head, body, and tail. Green represents the true segmentation and red represents the estimate. Human reproducibility defined a different point for the head/body split and rater 2 under-segmented the tail of the hippocampus and the tip of the head compared with rater 1. OVAL-30 produced more local errors than OVAL. Images were rotated along the axis of the hippocampus, gaps between the head, body, and tail are exaggerated for visualization.
