Implicit surface reconstruction from 2D CT scan sections

In this paper a new method, using the skeleton-based implicit model, is introduced for shape reconstruction of objects from a set of data points organized in planar sections. To reduce complexity and computation time, the objects are described by a uniform field function and a “3D weighted skeleton”. The 3D skeleton is composed of planar elements and is deduced from the 2D Voronoi skeleton of each section. The weights are distances creating a non uniform offset of the skeleton
