Harmonic Field-Point-Line Framework for Precise Dental Mesh Segmentation

2026-08-24

Abstract excerpt

<title>Abstract</title> <p>Three-dimensional tooth segmentation is essential for orthodontic CAD, yet achieving high accuracy and efficiency remains challenging with complex models. We propose a three-stage, concavity-aware harmonic field–point–line framework, which includes local tooth region extraction via adaptive ellipsoidal cropping, vertex-level scoring using a proposed Locational Strength metric, and close...
