Segmentation Boundary Reproducibility

Methods for measuring segmentation agreement when boundaries are uncertain and small contour shifts alter derived imaging features. Which overlap, surface-distance, boundary-uncertainty, and feature-stability measures should guide reproducibility assessment?

What does feature stability protect against?

Why should an imaging feature remain stable across both plausible segmentation boundaries and acquisition settings before it supports a radiogenomic association? I’m trying to separate protection against contour uncertainty from protection against scanner or protocol dependence.
