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]
