(f) Region growing:
Region growing provides the capacity to split the segmentation into separate
objects. The separation of masks into different parts is obtained by region growing
method. The floating pixels can also be eliminated.
(g) Calculate 3D:
Calculate 3D is used for transformation of the data from 2D images into 3D
model [

].
(h) Meshing:
Meshing is needed in order to raise the quality of the triangles so that the pre-
processor of an FEA package can build a tetrahedron mesh from them. In other
words meshing provides a better geometric quality.
(i) Material assignment:
When the volumetric mesh is created in ABAQUS 6.10 from the remeshed
object, this volume mesh is loaded in MIMICS for material assignment.
(j) Converting to STL files:
3D solid model can be directly converted into STL format for use in subsequent
rapid prototyping process. The STL files provide interface options via triangulated
formats: Binary STL, ASCII STL. By using this, a triangle mesh will be generated
