The mesh generated has to fit to the surface, without distorting the form; meanwhile the panels have to preserve their planarity in order to prevent any brittle failure due to warping.
A cylinder is fit to the surface of the geometry, so the coaxial deviations can be measured as shown in Fig. 8.
Volume measurements are voxel counts, surface measurements were derived from the summed area of a skin of triangles fitted to the surface voxels of the data set.
(Consistent results were obtained for λ = [0.03, 0.07].) A 2-D TPS is fit to the surface, where the number of control points used is determined by the size of the surface along each axial dimension.
To compensate for the two different artifacts seen in the dataset, the flattening is done in two steps (see Fig. 3): A 2-D TPS is fit to the surface, where the number of control points used is determined by the size of the surface along each axial dimension.
Surface fits to the experimental data are also presented for communication purposes.
A 2-D TPS is fit to the segmented surface from each of the datasets to create a 3-D interpolated isotropic surface.
In the case of optic nerve head (ONH) centered scans (where the surfaces become indistinct at the optic disc), a second 2-D thin-plate spline is fit to the new surface.
Open image in new window Fig. 2 Surface roughness average (Ra): the arithmetic mean roughness of all points from a plane (centre line) fitted to the test surface .
Laminates, also known as veneers, are fitted to the front surface of each tooth after it has been shaved down half a millimeter, the thickness of a fingernail.
The fine-jet gas flow is characteristic of fine-porous separators tightly fitting to the electrode surface.
