Abstract: A method for three dimensional reconstruction cranio-facial structure from 2D CT slices is proposed in this work. The method involves preprocessing of the individual slices, contour finding, 3D coordinate generation, Delaunay triangulation and redundant tetrahedron removal. The results are compared with standard marching cube algorithm and with standard commercial 3D software. The performance is studied based on time complexity and improvement in resolution.

Keywords: Delaunay triangulation; convex hull; marching cubes; point cloud; anatomical facial reconstruction; CT slices; computed tomography; 3D reconstruction; cranio-facial structure; preprocessing; contour finding; 3D coordinate generation; redundant tetrahedron removal; face reconstruction.
