fit_spline_xform(1) The Computational Morphometry Toolkit fit_spline_xform(1)


fit_spline_xform - Fit Single B-Spline Transformation to Concatenated Transformation List


fit_spline_xform InputImage XformList


Fit a parametric nonrigid transformation (B-spline free-form deformation) to a list of concatenated, optionally inverted, transformations.


Global Toolkit Options (these are shared by all CMTK tools)

Write list of basic command line options to standard output.
Write complete list of basic and advanced command line options to standard output.
Write list of command line options to standard output in MediaWiki markup.
Write man page source in 'nroff' markup to standard output.
Write toolkit version to standard output.
Write the current command line to standard output.
Set verbosity level.
Increment verbosity level by 1 (deprecated; supported for backward compatibility).
Set maximum number of parallel threads (for POSIX threads and OpenMP).

Fitting Options

Number of levels in the multi-level B-spline approximation procedure. [Default: 1]
Fit affine transformation first, then initialize spline with it.
Final control point grid spacing of the output B-spline transformation. [Default: 0]
Final control point grid dimensions (i.e., number of controlpoints) of the output B-spline transformation. To be provided as 'dimX,dimY,dimZ'. [Default: NONE]

Input Options

Numerical tolerance of B-spline inversion in mm. Smaller values will lead to more accurate inversion, but may increase failure rate. [Default: 1e-08]

Output Options

Path for the output transformation. [Default: NONE]
