The software for this is on avaliable on request from eep1ph
ELF is the first version of our Ellipses finder: ELF runs using
two routines
Canny2Eseg - Curve Segmenter
Eseg2Ell - Ellipse finder
ELF segments the canny strings and produces the elliptical output.
There are a number of parameters that can be set for each and
a description of these is given when the programmes are run using
no options.
See Below
Canny2Eseg,Eseg2Ell
There may be Many!!!!!!!!.
Please note some bugs exist, I hold no responsibility for any mistakes
caused through the use of these programmes or as a consequence of using
these programmes.
I am interested in finding images that produce incorrect data
or produce errors if you find any images that do please write
to me so I can see them.
If all the strings are short or small i.e. if the only ellipse is
small and far away it may produce no ellipses, don't be surprised
if this occurs. In later version I will tell you if no ellipses
have been found.
The programmes can all be found in my bin
/user/eevssppg/eep1ph/bin
to run ELF type....
file is the CannyLists of an image in gf format.
ELF file
The Canny_file can be created by
canny -g file < Image_file > /dev/null
The ELF programme will produce a number or files
file.el.gf - Ellipse before and after merging
file.seg.gf - Curved Segments
ELF Auto run xgf to display the object.
the xgf field are
CannyLists - CannyStrings
Curved_Segs - Segemented Strings from Canny_file.seg.gf
Ellipses - Ellipses from Canny_file.el.gf
Merged_Ellipses - Ellipses from Canny_file.el.gf
Ellipses_Coords - Major and Minor Axes drawn
Ellipses_Center - Center point drawn

PGMtoELF image.pgm
produces elliptical output from PGM input
PGMtoELFMatch image.pgm
produces elliptical output from PGM input, but tries some matching
of curves beforehand (still in early stages of development, not
recommended for use)
ELF is a shell script and so if you look at it you will see that
it runs a series of programmes. These programmes do have options
and you may be interested in changing some of them to suit your needs.
A list of the usage is shown below which is given when no options are
placed on the command line.
