VGDM: Visual Localization-Guided 3D Dental Segmentation via Extrinsic–Intrinsic Bridging

Hanbin Fang, Shidong Yang, Fan Duan, Shuo Wang, YanHeng Zhou, Li Chen

IJCAI 2026

3D dental segmentation is a key task in digital dentistry. In real intraoral scans data (IOS), occlusion, scanning noise, and reconstruction artifacts often break down the geometric separation structure between teeth, resulting in adjacent teeth being incorrectly merged or a single tooth being over-

T-CorresNet: Template Guided 3D Point Cloud Completion with Correspondence Pooling Query Generation Strategy

Fan Duan, Jiahao Yu, Li Chen*

ECCV 2024poster

"Point clouds are commonly used in various practical applications such as autonomous driving and the manufacturing industry. However, these point clouds often suffer from incompleteness due to limited perspectives, scanner resolution and occlusion. Therefore the prediction of missing parts performs…
