IWCIA'17 is the eighteenth of a series of international meetings on combinatorial image analysis. It will take place in Plovdiv, Bulgaria, June 19-21, 2017. Previous meetings were held in Paris (France, 1991), Ube (Japan, 1992), Washington DC (USA, 1994), Lyon (France, 1995), Hiroshima (Japan, 1997), Madras (India, 1999), Caen (France, 2000), Philadelphia (USA, 2001), Palermo (Italy, 2003), Auckland (New Zealand, 2004), Berlin (Germany, 2006), Buffalo, NY (USA, 2008), Playa del Carmen (Mexico, 2009), Madrid (Spain, 2011), Austin (Texas, 2012), Brno (Czech Republic, 2014), and Kolkata (India, 2015)

Image analysis is a scientific discipline providing theoretical foundations and methods for solving problems appearing in a wide range of areas, as diverse as medicine, robotics, defense, and security. As a rule, the processed data are discrete; therefore, the "discrete approach" to image analysis appears to be a natural one and has an increasing importance. It is based on studying combinatorial properties of the considered digital data sets. Combinatorial image analysis often features various advantages (in terms of efficiency and accuracy) over the more traditional approaches based on continuous models requiring numeric computation.

The scientific program of the workshop consists of keynote talks, contributed papers, and posters.

The conference proceedings are published in the Springer's "Lecture Notes in Computer Science" series, Vol. 10256.
LNCS 10256

After the Workshop, the authors of the best ranked papers will be invited to submit extended versions of their works for publication in special journal issues. A thematic special issue of Information Sciences - Elsevier (impact factor 4.832) has already been arranged.


The Workshop is a forum for current research on the following (or similar) research subjects which are directly or potentially applicable to image analysis:
  • Combinatorial problems in the discrete plane and space; Lattice polygons and polytopes
  • Digital/combinatorial geometry and topology
  • Digital manifolds; Geometry of digital curves and surfaces
  • Analysis and processing of digital surfaces with singularities (such as "pinched digital surfaces")
  • Homotopy of digital manifolds; thinning algorithms and skeletons
  • Boundary tracking of digital solids; Geometric characteristics of object boundaries
  • Multigrid convergence analysis of metric-based descriptors
  • Tilings and patterns; Combinatorial pattern matching
  • Computational geometry and imaging sciences
  • Integer programming, linear programming, and graph theoretic models and approaches to problems of image analysis
  • Image representation, segmentation, grouping, and reconstruction
  • Processing "very large" digital pictures; Methods for image compression
  • Parallel architectures and algorithms
  • Fuzzy and stochastic image analysis
  • Discrete tomography
  • Grammars and models for image or scene analysis and recognition; cellular automata
  • Mathematical morphology and image analysis
  • Applications in medical imaging, biometrics, computer vision, image understanding, robotics, metrology, and others
The submitted papers are expected to meet high standards satisfying serious evaluation criteria. Each paper will be reviewed thoroughly by at least two members of the Program Committee. Double-blind review process will be applied to ensure maximal objectiveness.

Short communications

Short communications presenting work in progress or ideas for possible investigations are also accepted. They provide an opportunity to open a discussion, find collaborators, or receive input on a new idea. Accepted short communications are published in a separate book and will be presented at a poster session. After the workshop, the authors will have the possibility to submit full papers to the special journal issues.
