vtopoclass(1i)
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.
