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]
