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

            Write man page source in 'nroff' markup to standard output.

            Write toolkit version to standard output.

            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).

       --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>
