Asymmetric parallel 3D thinning scheme and algorithms based on isthmuses

摘要: A new generic scheme for asymmetric, topology-preserving 3D parallel thinning.New curve, surface, and curve-surface thinning algorithms based on isthmuses.Comparison of the proposed algorithm with all existing methods same class.Our curve outperforms ones respect to robustness.Variant our method that allows skeleton filtering isthmus persistence. Critical kernels constitute a general framework settled in context abstract complexes study any dimension. We take advantage properties this framework, propose obtaining thin skeletons from objects made voxels. From scheme, we derive produce or surface skeletons, notion 1D 2D isthmus. compare published kind, quantitative criteria. Our experiments show largely other noise sensitivity. Furthermore, how slightly modify include parameter controls effectively pruning
