IWCIA’20 is the twentieth of a series of International Workshop on Combinatorial Image Analysis. It will take place in Novi Sad, Serbia, July 16-18, 2020. 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), Kolkata (India, 2015), Plovdiv (Bulgaria, 2017) and Porto (Portugal, 2018) .

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.

After the Workshop, the authors can submit extended versions of their works for publication in special journal issue: Journal of Combinatorial Optimization of Springer has already been arranged.

The previous IWCIA proceedings are available on the SpringerLink website here.


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.

We would like to take the opportunity to honor the memory of the former IWCIA conference chairs, Program Committee members, and area leaders Rani Siromoney and Reinhard Klette who recently passed away.

Prof. Rani Siromoney was born in India in 1929. She was on the faculty of the Department of Mathematics, Madras Christian College, Chennai, India, for 37 years and later a Professor Emeritus. She was an accomplished researcher and a devoted teacher, published widely in journals of repute. Prof. Siromoney was recognized worldwide for her research in a branch of theoretical computer science, known as Formal Languages and Automata Theory and was one of the leading authorities in this area. She mentored numerous researchers who are now among the most prominent scientists in the field. In 1999, she successfully organized the 6th edition of IWCIA in Chennai, India. Professor Siromoney passed away on September 28, 2019.

Prof. Dr. Reinhard Klette, a fellow of the Royal Society of New Zealand, was born in Germany in 1950. He served as the director of the Centre for Robotics & Vision at Auckland University of Technology, New Zealand. He was renowned for his work in the area of computer vision. His numerous publications include the books “Digital Geometry” (co-authored by the late Azriel Rosenfeld), “Computer Vision for Driver Assistance,” “Concise Computer Vision,” “Computer Vision – Three-Dimensional Data from Images,” and many others. Numerous graduate students developed suc- cessfully as scientists under his supervision. He was the founding editor in chief of the Journal of Control Engineering and Technology (JCET) and an associate editor of IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI). In 2004, Prof. Klette organized the 10th edition of IWCIA in Auckland, New Zealand. He passed away on April 3, 2020.
