       ing] input output subject

DESCRIPTION

       This tool applies spatial filtering operators, including cnotent-sensitive opersators, based on selective Gaussian kernels.

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.

       --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
       --gaussian <float>, -g <float>
	    Gaussian filter width (sigma) [Default: disabled]

       --radius <float>, -r <float>
	    Filter radius (truncated outside) [Default: 2]

       --mask <string>, -m <string>
	    Binary mask file name [Default: NONE]

       --studholme, -s
	    Use Studholme's consistent filtering

       --bin-width <float>, -b <float>
	    Intensity bin width for consistent filtering [Default: 10]

       --rohlfing, -R
	    Use Rohlfing's single-image consistent filtering

       --intensity-gaussian <float>, -G <float>
	    Intensity gaussian sigma for consistent filtering [Default: 0]

   Image/Transformation Database
       --db <string>
	    Path to image/transformation database that should be updated with the newly created image.	[Default: NONE]
