Evaluation Metrics

The segmentation performance is evaluated in four aspects following:

1. Dice Similarity Coefficient (DSC): DSC is used to evaluate the area-based overlap index.
2. Hausdorff distance (HD): HD is used to evaluate the coincidence between the segmented surface and target
   surface.
3. Relative Volume Difference (RVD): RVD provides information about the volume differences between segmented
   and reference regions of the ICH.
4. The  Normalized Surface Dice (NSD)
   

Ranking Method

The ranking scheme includes the following steps:

1. Calculate the DSC, HD, NSD and RVD for all cases.
2. Rank the DSC, HD, NSD and RVD separately.
3. Average these rankings.
4. Tie if the rankings are equal.
