fit_affine_xform(1) Fit Single Affine Transformation to Concatenated List

SYNOPSIS

fit_affine_xform InputImage XformList

DESCRIPTION

Fit a linear affine transformation to a list of concatenated, optionally inverted, transformations.

OPTIONS

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

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

Input Options

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

Fitting Options

--rigid
Fit rigid transformation (rotation and translation only) using SVD.
--affine
Fit full affine transformation (rotation, translation, scales, shears) using pseudoinverse. [This is the default]

Output Options

--output <transformation-path>, -o <transformation-path>
Path for the output transformation. [Default: NONE]
