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.

1980.

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.
