IAPR International Conference on Discrete Geometry and Mathematical Morphology (DGMM), May 24-27, 2021

The IAPR International Conference on Discrete Geometry and Mathematical Morphology (DGMM) will be held on May 24 –27, 2021. This is the first joint event between the two main conference series of IAPR TC18, the International Conference on Discrete Geometry for Computer Imagery (DGCI), with 21 successful previous editions, and the International Symposium on Mathematical Morphology (ISMM), with 14 successful previous editions. DGMM offers the opportunity to share high quality research results within the fields of discrete geometry and mathematical morphology. We are delighted to host DGMM 2021 at the Centre for Image Analysis, Department of Information Technology, Uppsala University, Sweden.

Due to the COVID-19 pandemic, DGMM 2021 will be a fully digital remote event.


The main topics of interest include (but are not limited to):

  • Discrete Geometry and Combinatorial Topology: grids, discrete objects, discrete model properties, digitization schemes, geometric transforms, metrics and distance transformation, skeletons, discrete tomography, etc.
  • Image Segmentation and Discrete Shape Analysis: watershed segmentation, hierarchical segmentation, color and multi-channel image segmentation, texture segmentation, discrete and combinatorial tools for segmentation and analysis, discrete shape representation, recognition and analysis, clustering of spatial data.
  • Algebraic Theory: morphology on complete lattices and semilattices, representation of morphological operators, fuzzy morphology, connected operators, morphology on graphs, morphology on surface meshes and Riemannian manifolds.
  • Nonlinear Scale Space Theory: morphological decompositions, morphological PDEs, level set methods, morphological wavelets, morphological regularization.
  • Random sets Theory and Geometrical Probability: Boolean model for sets and functions, stochastic simulation of random media, etc.
  • (max,+)-Mathematics and Idempotent Analysis for Image and Signal Processing.
  • Image Filtering: color and multi-channel morphology, morphology on tensor fields, geodesic transformations, adaptive morphology, attribute filtering.
  • Computational Mathematical Morphology and Discrete Geometry: algorithms, architectures, data structures and programming paradigms for efficient implementation of morphological and discrete geometric operators and tools.
  • Applications: astronomy, geosciences and remote sensing, (bio)medical imaging, material science, data analysis, document processing, content-based information retrieval, video surveillance, industrial control, visualization.

Both theoretical and application-focused contributions related to these topics are welcome.


All submitted papers will be subject to a full peer-review. Accepted papers will be included in the conference proceedings, published in the Lecture Notes in Computer Science series by Springer.
