Curve Skeletonization in Continuous Domain for Meshes and Point Clouds

Researchers introduced CSCD, a continuous-domain curve skeletonization framework for 3D meshes and point clouds.

CSCD generalizes skeletonization through local separators, with CSCD-M for meshes and CSCD-PC for point clouds.

The mesh version uses intrinsic triangulation, while the point-cloud version uses tufted Laplacians to reduce discretization error.

The paper reports stronger robustness and competitive or better results on benchmarks and downstream shape analysis tasks.
