STAR-Edge extracts thin-walled edge points from unstructured point clouds by representing local neighborhoods as spherical curves, then classifying edges and refining positions with estimated normals. On the authors’ test at resolution 0.5, it achieves F1 0.7013 versus RFEPS’s 0.2625 and ECD 0.0587 versus 1.4392; RFEPS has higher recall. Results apply to this dataset and do not isolate the curve’s contribution.
