WlzCMeshTrExpansion
Name
WlzCMeshTrExpansion - computes strain tensors for the given conforming mesh transform.
Synopsis
WlzCMeshTrExpansion [-h] [-i] [-E|T|V] [-I] [-L] [-n] [-o<out file>]
                    [<input file>]
Options
-h Help, prints usage message.
-i Output spatial domain image not a conforming mesh.
-I Use transform inverse.
-E Use maximum strain tensor eigenvalue.
-L Use kriging rather than barycentric interpolation./td>
-T Use strain tensor trace.
-V Use element volume (default).
-n Normalise expansion factors./td>
-o Output object file.
Description
Examples
Computes the expansion of each element of the given mesh transform. The expansion may be output as a mesh with scalar values attached to the mesh elements or as a 2D spatial domain object with image values. If requested the image values are normalised so that: [0:max(abs(min),abs(max))] -> [128:25] By default all files are read from the standard input and are written to the standard output.
WlzCMeshTrExpansion -o meshexp.wlz -i -n meshtr.wlz
Creates a new spatial domain (image) object (written to meshexp.wlz) with the mesh expansion factors normalised to fit within the unsigned byte range and with 0 to the value 128.
