NAME

registration - Rigid and affine registration

SYNOPSIS

registration ReferenceImage FloatingImage

DESCRIPTION

This program performs rigid and affine image registration using multi-resolution optimization of voxel-based image similarity measures.

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.

--xml

Write command line syntax specification in XML markup (for Slicer integration).

--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).

Automation Options

--auto-multi-levels <integer>

Automatic optimization and resolution parameter generation for <n> levels [Default: 0]

Optimization settings

--exploration <double> , -e <double>

Exploration [initial optimizer step size] [Default: 8]

--accuracy <double> , -a <double>

Accuracy [final optimizer step size] [Default: 0.1]

--stepfactor <double> , -f <double>

Factor for search step size reduction. Must be > 0.0 and < 1.0 [Default: 0.5]

--delta-f-threshold <double>

Optional threshold to terminate optimization (level) if relative change of target function drops below this value. [Default: 0]

Image resolution parameters

--sampling <double> , -s <double>

Image sampling (finest resampled image resolution) [Default: 1]

--coarsest <double>

Upper limit for image sampling in multiresolution hierarchy [Default: -1]

--omit-original-data

Do not use original data in full resolution, omit final stage in multiresolution hierarchy, thus reducing computation time.

Transformation parameters

--dofs <integer>[,<integer>,...]

Add number of degrees of freedom [can be repeated]

--dofs-final <integer>[,<integer>,...]

Add number of degrees of freedom for final level only [can be repeated]

--no-switch , -n

Do not auto-switch reference and floating image for improved computational performance

--initxlate , -i

Initialized transformation by translating floating image FOV center onto reference image FOV center

--initial <transformation-path>

Initialize transformation from given path [Default: NONE]

--initial-is-inverse

Invert initial transformation before initializing registration

Image data

--registration-metric

Registration metric for motion estimation by image-to-image registration. Supported values: "nmi", "mi", "cr", "msd", "ncc", where the default is "nmi", or use one of the following:
--nmi

Normalized Mutual Information metric [This is the default]

--mi

Standard Mutual Information metric

--cr

Correlation Ratio metric

--msd

Mean Squared Difference metric

--ncc

Normalized Cross Correlation metric

--match-histograms

Match floating image histogram to reference image histogram.
