NAME
       vselbig - select largest labelled component

SYNOPSIS
       vselbig [infile] [outfile]

DESCRIPTION
       vselbig selects the largest labelled component of a labelled image.

       The  input image must be a labelled image of type "ubyte" or of type "short".  Typically, it has  been created by some labelling algorithm,
       such as "vlabel2d", "vlabel3d", or some segmentation routine, e.g. "visodata".  vselbig then creates a binary output image in which  pixels
       belonging to the largest component (i.e. the most frequent label value) have value "1" and all other pixels have value "0".

TYPICAL PROCESSING CHAIN
       The following is a typical processing chain:

       visodata -in image.v | vbinarize -min 2 -max 2 | vlabel3d | vselbig -out result.v

       This  chain will segment the input image (visodata). It will then extract the class labelled "2" (vbinarize) and perform a connected compo-
       nent analysis of this class (vlabel3d). Finally, the largest connected component of class "2" is selected using vselbig.

COMMAND LINE OPTIONS
       vselbig 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.
