Hi,
Could someone please clarify what is meant by 'Multi-level' in the context of evaluation of Dice and HD metrics?
Quote from evaluation page: " Multi-level Dice Similarity Coefficient (Dice): Dice is used to evaluate the area-based overlap index. Multi-level Hausdorff distance (HD): HD is used to evaluate the coincidence of the surface for stable and sensitive to outliers."
Many thanks!

We explained our multi-level evaluation criteria by email. Based on the submitted segmentation results, Dice and HD95 will be calculated in two levels. The pulmonary artery inside the lung is level ONE, and the pulmonary artery outside the lung is level TWO.

Thank you. What is the meaning of these two levels? how do you weigh their importance in the final score? Many thanks, Ashkan

It's more hard and meaningful to segment the PA inside the lung area. We prefer to give them higher weight.
