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
