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]
