Abstract:
The present paper deals with the discretization of microstructure initially
represented by a digital image obtained from computer tomography
or any other similar scanning device. The boundary voxels in the
digital representation are identified and then replaced
by a boundary triangulation of the similar resolution as the original
digital image. This triangulation is then subjected to recursive
subdivision to recover a smooth surface of the microstructure which is
then retriangulated according to a user specified resolution. Finally,
the interior of the microstructure is discretized. The performance of
the proposed approach is shown on an example.
