13th International Workshop on Graphics Recognition (GREC)

September 20-21, 2019
Sydney, Australie

GREC workshops provide an excellent opportunity for researchers and practitioners at all levels of experience to meet colleagues and to share new ideas and knowledge about graphics recognition methods. Graphics Recognition is a subfield of document image analysis that deals with graphical entities in engineering drawings, comics, musical scores, sketches, maps, architectural plans, mathematical notation, tables, diagrams, etc.

The aim of this workshop is to maintain a very high level of interaction and creative discussions between participants, maintaining a « workshop » spirit, and not being tempted by a « mini-conference » model.

GREC 2019 will continue the tradition of past workshops held at the Penn State University (USA), Nancy (France), Jaipur (India), Kingston (Canada), Barcelona (Spain),, Hong Kong (China), Curitiba (Brazil), La Rochelle (France), Seoul (Corea), Lehigh (USA), Nancy (France) and Kyoto (Japan).

The workshop will comprise several sessions dedicated to specific topics related to graphics in document analysis and graphic recognition. For each session, there will be an invited presentation describing the state of the art and stating the open questions for the session’s topic, followed by a number of short presentations that will contribute by proposing solutions to some of the questions or presenting results of the speaker’s work. Each session will be concluded by a panel discussion.

For this 13th edition, we would like to highlight three topics related to graphic recognition.
Three special sessions will focus on :

  • Music Scores analysis and recognition
  • Comics Analysis and Understanding
  • Sketch Recognition and Understanding.

We encourage the authors to submit papers on these topics.

However papers on the following topics are of course expected.


  • Analysis and interpretation of graphical documents, such as: Engineering drawings, floorplans, mathematical expressions, comics, maps, music scores, patents, diagrams, charts, tables, etc.
  • Recognition of graphic elements, such as symbols, logos, stamps, dropcaps, drawings, etc.
  • Identification and localization of graphical mark-ups and annotations in written documents.
  • Raster-to-vector techniques.
  • Graphics-based information retrieval.
  • Historical graphics recognition and indexing.
  • Forensics (Writer identification/verification) in graphic documents.
  • Description of complete systems for interpretation of graphic documents.
  • Datasets and performance evaluation in graphics recognition.
  • Authoring, editing, storing and presentation systems for graphics multimedia documents.
  • 3-D models from multiple 2-D views (line drawings).
  • Digital ink processing.
  • Sketch recognition and understanding.
  • Camera-based graphics recognition.
  • Graphics recognition in born digital documents.
  • Analysis of graphics on new digital interfaces.
  • Graphics detection and recognition in real scenes.
  • Graphics analysis in medical images

Guidelines for authors
For this edition, authors are invited to submit two types of paper :

  • Full papers describing complete works of research (up to 6 pages). They will undergo a rigorous review process with a minimum of 2 reviews considering the originality of work.
  • Short papers providing an opportunity to report on research in progress and to present novel positions on graphic recognition (up to 2 pages). Short papers will also undergo review and will appear in an extra booklet, not in the official proceedings. The booklet will be available on the GREC 2019 website.

Full papers will be published according to the same policy and conditions of ICDAR 2019 conference papers (format, length, publication site).
See http://icdar2019.org/paper-submission/ for more information.
Short papers have to respect the same format than full papers but within the limit of 2 pages.

Remarks : In the ICDAR USB proceedings, the GREC full papers will be located in a separate folder, but they will be indexed at IEEE Xplore.

Post-GREC publication

After the workshop, authors of the best long papers will be invited to submit an extended version of their work for publication in a special issue of IJDAR. The theme of this special issue will be decided according to the strong themes that emerge from the best papers presented at GREC. Further, there will be a possibility of accepting papers from outside the GREC workshop, in case they are aligned with the theme.
