WlzBasisFnTransformObj

Mapping and Analysis CD | WlzBasisFnTransformObj

Usage: WlzBasisFnTransformObj [-o< out object >] [-p< tie points file >]

      [-m< min mesh dist >] [-M< max mesh dist >]
      [-t< basis fn transform >] [-Y< order of polynomial >]
      [-g] [-h] [-q] [-s] [-y] [-B] [-D] [-G] [-L] [-T]
      [< in object >]

Options:
      -B Block mesh generation method (default).
      -D Output the mesh as postscript to the standard error output,
            may be useful for debugging.
      -G Gradient mesh generation method.
      -L Use linear interpolation instead of nearest neighbour.
      -m Minimum mesh node separation distance (default 10.0)
      -M Maximum mesh node separation distance (default 100.0)
      -R Restrict the transformation to only a basis function transform
            instead of the default which uses a least squares affine and
            basis function transform.
      -o Output object file name.
      -p Tie point file.
      -t Basis function transform object.
      -c Use conformal polynomial basis function if tie points are given.
      -g Use Gaussian basis function if tie points are given.
      -h Help, prints this usage message.
      -q Use multi-quadric basis function if tie points are given.
      -s Use thin plate spline basis function (default) if tie points
            are given.
      -T Output a basis function transform instead of a transformed
            object.
      -U Output a mesh transform instead of a transformed object.
      -y Use polynomianl basis function if tie points are given.
      -Y Polynomial order for oolynomianl basis function (default 3).

      Computes and applies Woolz basis function transforms.
      Tie points may be read from an ascii file with the format:
      < vertex x > < vertex y > < displacement x > < displacement y >
      Objects are read from stdin and written to stdout unless the filenames
      are given.
      Example: WlzBasisFnTransformObj -o tied.wlz -p points.tie myobj.wlz
      A thin plate spline basis function transform is computed from the
      tie points read from the file points.tie. This transform is then
      applied to the object is read from myobj.wlz. The resulting object
      is then written to tied.wlz.
