1. News for next event organisation: DGCI + ISMM

After the call for proposals of the first DGCI+ISMM event, the steering
committees are happy to announce that the Uppsala proposal (Sweden)
was retained to organize this new event that will be held in Fall
2020 (December 10-13, date to be confirmed). The event will be chaired by
Filip Malmberg (main chair), Nataša Sladoje (program chair) and Joakim
Lindblad (Organization Chair). The organisation team is completed by
advisors (Robin Strand, Ingela Nyström), honorary chair (Gunilla
Borgefors, Christer Kiselman) and assistant (Johan Öfverstedt).

2. DGCI and ISMM reports

DGCI report

The 21th IAPR International Conference on Discrete Geometry for
Computer Imagery, DGCI 2019, was held at ESIEE Paris, France, during
March 26-28 2019. This conference was organized by Michel Couprie,
Jean Cousty, Yukiko Kenmochi and Nabil Mustafa from the ESIEE Paris,
Université Paris-Est, France. The DGCI 2019 conference attracted 76
researchers. The scientific program consisted of 3 invited talks, 26
oral and 10 posters presentations during 3 days. This edition
attracted 50 submissions by authors from 20 countries: Australia,
Austria, Belgium, Brazil, China, France, Hungary, India, Iran, Italy,
Japan, The Netherlands, Peru, Poland, Russia, Serbia, Spain, Sweden,
UK, and USA

Three keynote speeches were given:

– Alexandre Xavier Falcão, from University of Campinas, Brazil, on “The Role of Optimum Connectivity in Image
Segmentation: Can the Algorithm Learn Object Information During the Process?”
– Longin Jan Latecki, from Temple University, USA, on “Computing Maximum Weight Cliques with Local Search on
Large Graphs with Application to Common Object Discovery”
– János Pach, from École polytechnique fédérale de Lausanne, Switzerland, on “The Blessing of Low

Congratulation to Loïc Crombez (from Université Clermont Auvergne - LIMOS, France) who obtains the best DGCI Student
Paper award for his article: Efficient Algorithms to Test Digital Convexity (co authored with Guilherme D. da Fonseca and Yan Gérard).

The full report will available online on the TC website:

ISMM report

The 14th International Symposium on Mathematical Morphology (ISMM
2019), was held in Saarbrücken, Germany, during July 8–10, 2019. The event
was organized by Bernhard Burgeth, Andreas Kleefeld, Benoît Naegel,
Nicolas Passat, and Benjamin Perret. The ISMM 2019 symposium attracted 70
researchers. The scientific program consisted of 3 invited talks, 24
oral and 16 posters presentations during 3 days. This edition
attracted 54 submissions by authors from 16 countries: Austria, Brazil,
France, Germany, Greece, India, Italy, The Netherlands, Pakistan, Serbia,
South Korea, Spain, Sweden, Tunisia, UK, and USA.
Three keynote speeches were given:

5. Upcoming events

A new tutorial on Digital Geometry has been accepted for presentation
during the ACPR2019. It will take place on the first day of the
conference (see and here “Digital Geometry
in Pattern Recognition: Extracting Geometric Features with DGtal and
Applications” presented by Bertrand Kerautret (Université de Lyon 2,
France) and Jacques-Olivier Lachaud (Université Savoie Mont-Blanc,

Also organized in conjunction with ACPR2019, a new workshop
is proposed including discrete geometry in its topics (submission
deadline 5 September):

The twentieth International Workshop on Combinatorial Image Analysis
will be held on Novi Sad, Serbia, 16-18 July 2020. The first CfP is
attached to this email and is available here: and you can
also access to workshop website:

6. New content of TC18 website

As announced during the TC18 presentations of DGCI a ISMM, a new
Project section was added to the site. The aim of this page is to
provide an overview of existing active (or past) projects with
relation to DG and MM (national, European or international) and also
to add proposition of new collaborations. If you want to add a
project, you can just send us an email with project information or
directly apply a Pull Request on this repository. Moreover, this page
can also be used to announce new project construction plans and help to
facilitate partnership.


The front page of the main site was also improved with a new twitter
feed and new account created. Don't hesitate to follow us on @IAPR_TC18.
By the way, if you are interested in sharing the twitter animation,
please contact us! (we are free to add new roles like "communication
board member").

The page organisation was adjusted to include the new "project" page
and a new "Report" page was added in order to propose a direct access
to all the activity reports written from 2013 (

7. Miscellaneous

For the people who miss this information, the new version DGtal 1.0 was released last March!

For people interested in Computer Vision and Machine Learning (CVML)
an new email list for scientific dissemination. See mail in this link:

After the two years activity reports written last year (see report from the page for the ExCo meeting that held at ICPR
2019, this year there are no interim report to do. However, we start
an equivalent draft to simplify the redaction of next final report for
the period 2018-2020.
