研究目的: |
本项目拟建立IOS数据库,结合3D牙齿点云的几何特征设计牙齿实例分割模型,结合探讨不同弱标记方式和策略对分割精度的影响;通过对比实验、消融实验明确注意力机制、迁移学习和医学先验对弱监督学习模型性能的影响。本项目的研究试图探寻基于弱标记和弱监督学习实现IOS自动分割的机制,为口腔正畸方案数字化设计奠定基础。 |

|
Objectives of Study: |
This project aims to establish an IOS database, design a tooth instance segmentation model based on the geometric features of 3D tooth point clouds, and explore the impact of different weak labeling methods and strategies on segmentation accuracy; By conducting comparative experiments and ablation experiments, we aim to clarify the impact of attention mechanisms, transfer learning, and medical priors on the performance of weakly supervised learning models. The research of this project attempts to explore the mechanism of IOS automatic segmentation based on weak labeling and weakly supervised learning, laying the foundation for the digital design of orthodontic solutions. |
