The goal of the project is to reconstruct three-dimensional shape of placentas, and provide shape characterization for exploring the relation between placental shapes and fetal growth. We investigate two types of surface reconstruction methods: implicit and explicit methods.  Our  approach can be applied to any unorganized set of points. This 3D level set method shrinks an initial guess to a smooth surface on the given data. Finally, some geometric descriptors, such as surface areas and volumes, are computed based on these reconstructed models for further shape analysis.
