Abstract:
Considering the dental CBCT images' characteristics, the method of deformable surface of 3D triangle mesh model is proposed. The method uses a deformable model which is initialized from an icosahedron and evolves to fit the teeth's surface by the application of the locally adaptive external forces computed from the image data and internal forces coming from the model itself. The experimental results indicate that the proposed method is robust and accurate.
