DGCI was organized by the laboratory SIC - "Signal, Image, Communications" of the University of Poitiers, Centre National de la Recherche Scientifique and Technical Committee 18 of the International Association of Pattern Recognition (IAPR). The series of DGCI conferences started in 1991 and is now the main conference of IAPR TC18.
For this edition, Eric Andres was the general chair, Pascal Lienhardt the program chair and Guillaume Damiand the publications chair. DGCI 2005 was sponsored by the Faculty of Science, the University of Poitiers, the Region of Poitou-Charentes and the IAPR. The conference venue was the IFMI building on the Futuroscope campus ground in Chasseneuil du Poitou, near the Futuroscope park.
DGCI 2005 attracted many excellent papers with 53 submitted papers from 21 countries. After careful reviewing by two and sometimes three reviewers, 36 papers were accepted, from which 22 were selected for oral presentation and 14 as posters. The conference brought together 84 participants, coming from 17 countries. As usual at DGCI conferences, there was a low cost registration for students.
This year's conference was organized in conjunction with the 5th Workshop on Graph-based Representations in Pattern Recognition (see related article in this issue). The GbR workshop aims at using graph-based structures in image analysis. There is a strong connection between the community interested in the GbR workshop and the discrete geometry community. For this reason—and for the first time— GbR and DGCI were organized in the same place with a common session of four papers, two of which were submitted to GBR and two to DGCI.
The talk and poster sessions covered topics such as reconstruction and recognition, discrete topology, uncertain geometry, visualization, discrete models and transforms, morphology and tomography including various applications.
Three invited speakers showed new, important views in the field of discrete imagery: Prof. Achille Braquelaire gave a talk devoted to "Representing and Segmenting 2D Images by means of Planar Maps with Discrete Embeddings: from Model to Applications"; Prof. Peter Veelaert gave a talk on "Uncertain Geometry in Computer Vision"; and Prof. Jean-Pierre Guedon spoke about "The Mojette
Transform: the First Ten Years". The conference was well organized, the program ran smoothly without any problem. The available infrastructure, including the audio/projections, computer equipment, Internet connection, worked according to high standard. The social program contained a reception and also a conference banquet, both of them had great success among the participants.
Proceedings of the conference are published by Springer in "Lecture Notes in Computer Science" #3429. Two special issues will come out soon: one in "Image and Vision Computing Journal" and the other in "Computer and Graphics".
The next DGCI Conference will held in Szeged, Hungary, November 8-10 2006, organized by the Dept. of Image Pocessinng and Computer Graphics, Univ. of Szeged, with Prof. Attila Kuba as General Chair.
