DGCI is the main conference of the IAPR Technical Committee on Discrete Geometry (TC18) and is held approximately every 18 months. The 16th edition of the International Conference on Discrete Geometry for Computer Imagery was held in Nancy, France, and was organized by the ADAGIo team of the LORIA laboratory (Lorraine research center in computer science and its applications).
DGCI2011 attracted many researchers (92 participants) from all around the world. Indeed, 70 papers were submitted, from 22 different countries, confirming the international status of the conference. Following a thorough reviewing process, remodeled from DGCI 2008, 40 papers were accepted and published in the Springer Lecture Notes in Computer Science Series (volume number 6607). Altogether, 20 papers were scheduled for oral presentation in single-track sessions, and 20 papers were presented as posters, with preliminary plenary sessions with very short oral presentations of these posters.
The contributions focused on models for discrete geometry, discrete and combinatorial topology, geometric transforms, discrete shape representation and analysis, discrete tomography, and discrete and combinatorial tools for image segmentation and analysis.
In addition, the program was enriched by three invited lectures, presented by internationally known speakers:
· Agnes Desolneux (CNRS researcher, MAP5, Paris Descartes University, France), gave a talk on “A probabilistic grouping principle to go from pixels to visual structures”. She presented the translation of the principle of visual perception (Helmholtz principle) into a computational tool for image analysis.
· Jarek Rossignac (Professor, GVU Center, Georgia Tech, USA), was the IAPR invited speaker of the DGCI2011 conference. He proposed an overview of his work centered on ball-based approaches for analyzing, transforming, comparing, and morphing shapes. More information can be found here: www.gvu.gatech.edu/~jarek/papers.html
· Jean Serra (Professor Emeritus, ESIEE-LIGM, Paris, France) gave a talk about “Hierarchical Segmentations”. He described segmentation approaches based on the hierarchies of partitions of an image and on the minimization of energies satisfying the condition of hierarchical increasingness.
For the first time, DGCI hosted a demonstration session. The purpose of this successful session was to provide the opportunity to present and share effective applications related to the main topics of DGCI. Fourteen demonstrations were presented including a new Discrete Geometry Library, named DGtal (liris.cnrs.fr/dgtal/).
For the second time, the DGCI steering committee attributed an award for the Best Student Paper. The winner is Wagner Fortes for the paper: “Bounds on the difference between reconstructions in binary tomography”, Kees Joost Batenburg, Wagner Fortes, Lajos Hajdu, Robert Tijdeman
Following the conference, two special issues in the journals "Discrete Applied Mathematics" and "Computer Vision and Image Understanding" will be specially edited. Another special issue is proposed in the on line journal "Image Processing On Line".
The social program proposed a guided tour “Nancy, from the Middle Age to Renaissance” on the first evening, including an evening buffet. The gala dinner was held in the Town Hall located on the famous Stanislas Square (on UNESCO’s World Heritage List).
The next DGCI conference will be held in Seville, Spain, March 20-22, 2013, organized by the Andalusian research group Combinatorial Image Analysis (“CIA” research group) of the Applied Math Department of the Seville University, with Rocio Gonzalez-Diaz and Maria Jose Jimenez as Co-Chairs.
