NAME

       vtopoclass - perform a topological classification

SYNOPSIS

       vtopoclass [-option ...] [infile] [outfile]

DESCRIPTION

       vtopoclass performs a topological classification on a binary input image and produce a labelled output image.

       Typically, this program is applied to a skeletonized binary image.  It will attribute a label to each foreground voxel, which characterizes
       its topological type.

       The input image must be of type bit. The output image will be of type ubyte.

       Output codes are the following:

		  1:  interior point
		  2:  isolated point
		  3:  border point
		  4:  curve point
		  5:  curves junction
		  6:  surface point
		  7:  surface/curve junction
		  8:  surfaces junction
		  9:  surfaces/curve junction

COMMAND LINE OPTIONS

       vtopoclass accepts the following options:

       -help	      Prints a message describing options.

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

       -out outfile   Specifies where to write the output images as a Vista data file.

       Input and output files can be specified on the command line or allowed to default to the standard input and output streams.
