Help for COMPTAB

PURPOSE:
comptab creates an IBIS tabular file from a connected component image and
from 0 to 48 registered brightness or difference images.  The connected
component image is a halfword image, usually created by program CONCOMP.
The registered images can be byte or half.  The IBIS tabular file that is 
output has one record for each connected component and the following
columns:

1.  The component number
2.  The count of pixels in the component, can be converted to area
3.  The line number of the first pixel scanned (in l,s order) of the component
4.  The sample number of the first pixel scanned
5.  The diameter in pixels of the component
6.  The average brightness or pixel value of the component in the 1st input image
7.  The average brightness or pixel value of the neighborhood of the component
    in the 1st input image
8.  The average brightness or pixel value of the component in the 2d input image
9.  The average brightness or pixel value of the neighborhood of the component
    in the 2d input image
etc

the last 10 columns are set to 0.0 to allow room for user calculation.

If a SIZE parameter is used, it applies to all of the input images.

EXECUTION:

Example

comptab INP=(A,B,C) OUT=D  A is the connected component image.  B and C are
                          registered brightness images. D is the output tabular file

OPERATION:

The statistics are read into an array from the input images.  The output
statistics are calculated and then written to an IBIS file.
 TIMING: 

all algorithms are linear with the image area.
