NAME
       vgenus3d - compute the genus of a 3D binary image

SYNOPSIS
       vgenus3d  [-option ...] [infile] [outfile]

DESCRIPTION
       vgenus3d  computes  the Euler number (genus) of a 3D binary source image.  It prints the result on stderr.  It produces no output file. The
       source image must be of type "VBit".  The input image must contain more than two bands.	Lee's algorithm only works if no  black  voxel	(a
       "set" voxel) touches the image border.

       The Input file can be specified on the command line or allowed to default to stdin.

COMMAND LINE OPTIONS
       vgenus3d accepts the following options in any order:

       -help	      Causes vgenus3d to print out a message describing its options.

       -in infile     Specifies the Vista data file containing the input images.

       -n n	      Specifies the type of neighbourhood system (6 or 26).  Default: 26.
