levelset(1) The Computational Morphometry Toolkit levelset(1)
NAME
levelset - Levelset segmentation
SYNOPSIS
levelset InputImage OutputImage
DESCRIPTION
Levelset-type segmentation of foreground/background using minimum regional variance energy
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).
Main Options
--binarize, -b
Binarize levelset and write as byte mask, rather than write floating-point levelset function itself.
These parameters control the initialization of the levelset function
--scale-initial-sphere <double>
Scale factor to reduce or increase the size of the initial foreground region sphere. [Default: 1]
These parameters control the evolution of the levelset function
--iterations <integer>, -n <integer>
Maximum number of iterations [Default: 100]
--force-iterations, -f
Force given number of iterations, even when convergence has been detected
--filter-sigma <double>, -s <double>
Gaussian filter sigma in world coordinate units (e.g., mm) [Default: 2]
--delta <double>, -d <double>
Time constant for levelset evolution; must be > 0; larger is faster [Default: 0.1]
--levelset-threshold <double>, -t <double>
Levelset threshold: levelset function is truncated at +/- this value [Default: 1]
Image/Transformation Database
--db <string>
Path to image/transformation database that should be updated with the newly created image. [Default: NONE]
