Subject: Software to detect symmetry/principal axes?

I'm trying to estimate axes of symmetry and/or principal axes of
fairly simple objects, starting from intensity images.  Any
preprocessing (e.g.  edge detection, grouping) is acceptable.  If you
know of any such software available to researchers, I'd appreciate an
email...

Thanks in advance,
Raja.

Subject: Volumes between Two Interpolated Surfaces

I need compute volume between two interpolated surfaces in order to
see how close they are. Is there any way to calculate reasonably
accurate volume?  I will appreciate any pointer to a program to do
that in any computer languages.

Subject: Aspect graph generation algorithms sought

I am looking for algorithms for computing the aspect graphs for 
3-D objects. I am interested in:
	a) ABOVE ALL, public domain software. There does not seem to
	   be much around.
	b) papers or reports with detailed algorithm descriptions;
	c) survey papers about visual potential.
My objects are obtained by union, subtraction and intersection of
straight linear generalized cylinders with polygonal section.
Simple cylinders are approximated by facetted polyhedra but real
curved surfaces could be a future target.

My problem is PRACTICAL: I REALLY have to generate aspect graphs
to investigate applications in automated inspection. "Simple but useful"
therefore preferred to "fancy but unimplemented".
I will summarize any results for the List as soon as possible.

Greetings:

I am looking for some pointers to algorithms for recognizing barcode
(3of9) patterns from a bitmap file.  I know C quite well but do not
have the formal computer science training necessary to get the job done.

Any help will be very much appreciated.

Hi,
I am looking for a technical report of the Academia Sinica, Taipei, Taiwan.

Authors: C.-S. Lin, C.-F. Wang, J.S. Huang
Title:   A new Chinese Character Thinning Algorithm on Tracing the Boundary.

			ECCV-92 GENERAL PRESENTATION

The "Second European Conference on Computer Vision" (ECCV-92) will take  place 
in Santa Margherita Ligure, a pleasant resort in the Italian Riviera  very 
close to Genova, Portofino and the "Cinque Terre", in conjunction with  the
5th Centennial Celebrations for the discovery of America by Cristoforo Colombo.
The announcement of this conference through the Call for Papers  has generated 
308 proposed contributions. The requirement set by the Programme Committee 
to maintain a single-track conference has limited  the number of accepted 
papers to 16 long papers, 41 short papers and 48  posters.
The proceedings will be published by Springer - Verlag in the "Lecture Notes
in Computer Science" series.
A copy of the video proceedings, edited by Giovanni Garibotto of Elsag - 
Bailey, will also be distributed to all registered participants.

The programme is articulated in three parts:
1) May 18th: an "Esprit Day" will be organized to present  ESPRIT projects
   active in the field of Computer Vision and its applications.
   Participation in the ESPRIT Day will be free of charge and will be open 
   to everyone interested in vision including participants from outside the 
   European Community. Organizations wishing to present their project or to 
   attend the meeting should contact: 
   Dr. Patrick Van Hove, 
   CEC DG XIII A4, Office BRE9-217,
   200 Rue de la Loi, B-1049 Brussels, Belgium.
2) May 19 to 22: ECCV-92 Conference.  
   Apart from the official programme  the participants will be given ample 
   space for informal activities such as the presentation of videos and the 
   participation in the "experimental  session" (see the following pages for
   further details).
3) May 23rd: three workshops will be organized  by the members of the  
   ESPRIT Basic Research Working Group on Vision to discuss some specific  
   topics of Computer Vision. Participation at these workshops is limited 
   in  number and requires a separate registration procedure. 
   For additional  information, contact:

   LIFIA-IMAG, 46 Avenue Felix Viallet,
   38031 Grenoble, France.
