Scope: the scope of the Morphology Digest list is to provide a
communication channel between people interested in
mathematical morphology and morphological image analysis.
Related posts such as publication and conference
announcements, algorithms, software, queries, and job
proposals are seeked. The list is moderated in the sense
that all messages are collected by the list owner and then
edited on a regular basis so as to create an edited digest
(maximum 6 per year). The digest is then sent to all list
subscribers but also appears at the following URL:
http://ams.jrc.it/mdigest
Subscribe: email to listserver@jrc.it with "subscribe mdigest" as
BODY of message and empty subject.
Unsubscribe: email to listserver@jrc.it with "unsubscribe mdigest"
+ email address as BODY and empty subject.
Submissions: email to mdigest@jrc.it with "submit" as subject. Please
note that only submissions from list subscribers will be read
by the editor.

1 ISMM'07: summary of event
=========================================================
From: banon at dpi.inpe.br
The Image Processing community has experienced a great semester in
terms of conferences in Brazil. In September, we had the ICDAR, the
International Conference on Document Analysis and Recognition, in
Curitiba, Parana. In October we had the SIBGRAPI, the Brazilian
Symposium on Computer Graphics and Image Processing (an international
conference in spite of the name) in Belo Horizonte, Minas Gerais; we
have also had the ISMM and the ICCV (International Conference on
Computer Vision), just after ISMM, in Rio de Janeiro. ISMM'2007 took
place at the beautiful beach of Copacabana, at the Luxor Regente
hotel. The hotel has a small place for conferences and it turned out
to be exactly the size we needed. We had the participation of 83
attendees (34 students, 44 professionals and 4 invited lecturers).
We had three days of intense activity:
1 Four invited lectures:
1.1 Dr. Robert Loce talked about some interesting problems in the
printing industry and how he and his team are solving them with
Mathematical Morphology.
1.2 Dr. Luc Vincent talked about the huge project of taking google
maps to street level and the several image processing problems they
are facing and solving.
1.3 Dr. Luis Velho talked about a unified topological and geometric
framework to deal with multiresolution solids.
1.4 Dr. Alexandre Falcão talked about the Image Foresting Transform
and the several applications of the transform from Image Processing to
Machine Learning.
2 Thirty seven paper presentations.
3 Thirty five short-paper presentations during the coffee-breaks (people
were busy even during the breaks).
4 A cocktail with Brazilian music and the presence of our friend
Dr. Marco Gubitoso performing some magic tricks to the attendees.
For ISMM'2007, two books have been produced:
1. A printed book published by MTC/INPE (São José dos Campos, Brazil).
It contains 38 full papers accepted for oral presentation at
ISMM'2007. The book was distributed to the ISMM'2007 attendees. Some
free copies are available for university and research laboratory
libraries, requests can be made to Gerald Banon (banon at dpi.inpe.br)
sending the full mail address of the library.
2. The on-line proceedings. These proceedings consist of two volumes.
Volume 1 contains the 38 full papers of the printed book.
Volume 2 contains the 35 extended abstracts accepted for poster
presentation.
Volume 2 has been announced on the ISMM'2007 web site:
http://ismm.dpi.inpe.br/2007
Besides that, there is going to be a special issue of IVC with the
best papers of ISMM'2007 (according to the Brazilian committee and the
input from the MM community). The authors of the selected papers will
be asked to submit a longer, more detailed and augmented version of
their work to IVC. The papers will be reviewed following the usual IVC
submission process, with the Brazilian committee members as guest
editors.
The ISMM organizers want to thank all the participants, the reviewers,
the sponsors CAPES, CNPq, FAPESP, National Instruments, and direct and
indirect collaborators for the success of the event.

2 Call for Proposals for the organisation of ISMM'09
=========================================================
From: cronse at dpt-info.u-strasbg.fr
During ISMM'2007, the ISMM Steering Committee met and discussed
possible locations for the next ISMM, for which we received several
suggestions. It was agreed that it should be held in 2009, but
before making a decision, a detailed review of all possibilities is
necessary.
Therefore we are now making an official call for proposals for the
organisation of ISMM'2009. These proposals will be discussed among the
ISMM Steering Committee members (who currently are Junior Barrera,
Isabelle Bloch, Renato Keshet, Petros Maragos, Fernand Meyer, Jos
Roerdink, Christian Ronse, Philippe Salembier, Pierre Soille, and
Hugues Talbot).
For the Steering Committee to have all the information necessary for
an informed choice, proposals should be as detailed as possible, in
particular they should address the following points:
1. Scientific and organisational strength of the proposed site;
provide detailed information concerning:
* the program chair;
* the local team that can help with the practical organisation;
* what administrative support the organiser's institution(s) can
provide;
* expected costs and subsidies;
* expected local and regional attendance.
2. Scientific arguments in favour of the proposal, in particular:
* strength of MM teams in the area;
* possible impact of ISMM on the image processing and vision
community, arising from this choice of location.
3. Timing and relation with other conferences to be held during the
same period, for example:
* ISMM as a standalone conference (like pre-2005 ISMMs);
* ISMM to be held just before or just after another conference held in
the same region (as happened for ISMM'2005 and 2007);
* ISMM sharing some sessions with another conference (like DGCI and
GBR);
* ISMM as an official satellite meeting of a larger conference.
Specify the related conference and the precise constraints associated
to the relation.
Please send your proposal to myself (cronse at dpt-info.u-strasbg.fr)
before December the 31st, 2007.
On behalf of the ISMM Steering Committee,
Christian Ronse

3 Birkhoff and the Alexandrov specialization order
=========================================================
From: cronse at dpt-info.u-strasbg.fr
One calls an "Alexandrov topology" a topological space where an
arbitrary intersection of open sets is open, or equivalently, every
point has a least neighbourhood. Alexandrov called it a "discrete
space".
The Alexandrov specialization theorem characterizes an Alexandrov
topology in terms of a quasi-order, that is, a reflexive and transitive
relation on that space. An Alexandrov topology on E and a quasiorder <=
on E correspond as follows:
- p <= q iff p belongs to the closure of {q};
- the open sets are the upper sets for <=, that is,
sets X with (p in X, p <= q) implies (q in X).
Moreover that quasiorder is an order relation (i.e., it is
antisymmetric) iff the topology satisfies the T0 separation axiom.
The usual reference for this result is [2], as well as Alexandrov's
later works (such as his topology book with Hopf, or his monograph on
combinatorial topology).
In fact, while developing his theory, Alexandrov discussed with
Birkhoff. In [1] Alexandrov proposed the axioms for a "discrete space"
and stated that it corresponded to a partially ordered set. Birkhoff
answered him in [3], and among other things stated that he was studying
similar structures in the framework of abstract algebra. Then Alexandrov
published his results in [2], in particular the specialization theorem.
The same year Birkhoff published [4], where he proved that a "complete
ring of sets" (family of sets closed under arbitrary union and
intersection, including void ones) corresponds to a quasiorder. A
"complete ring of sets" means exactly the same thing as "Alexandrov
topology", and the quasiorder given by Birkhoff is the same as the one
given by Alexandrov, but in another wording.
Birkhoff showed also that the "complete ring of sets" is a "complete
field of sets" (the family is also closed under complementation) iff the
quasiorder is an equivalence relation (i.e., it is symmetric); in
topological terms, it means that the open sets coincide with the closed
sets.
Therefore the specialization theorem attributed to Alexandrov is in some
way also due to Birkhoff.
