I high-level script that uses OTW codes to compute and fit image contours. The codes used in this package (and documented in these web docs), are:

 
thresh     == compute image threshold map 
fourcon    == computes map of 4-connected pixels 
edger_sqt  == computes image edge map using the square-trace algorithm  
cef        == fit ellipse to each computed contour set 




 The run script: find1.sh  

Usage:  find1.sh name.fits 1000.0  2 0.5 39.0 10 
                    a1       a2   a3  a4   a5 a6  
a1 - name of input image                       
a2 - threshold level                (thresh)  
a3 - size of scan bin               (thresh) 
a4 - fill percentage in smooth bin  (thresh)
a5 - starting region number         (edger_sqt)
a6 - fill percentage in smooth bin  (cef)
