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. TheĀ  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.
