Table 2.

Evaluation results of 500 subjects (%). The OA, mIoU, IoU (min) and IoU (max) of three cases are described in both segmentations (whole-heart and four-chamber segmentation). Abbreviations: OA, overall accuracy; mIoU, mean intersection over union; IoU (min), minimum IoU; IoU (max), maximum IoU.
