2) Call for papers of GREC 2023

15th International Workshop on Graphics Recognition (GREC)

August 25, 2023
San Jose, USA

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 sub-field 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 2023 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), Kyoto (Japan), Sydney (Australia) and Lausanne (Switzerland).

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.

We encourage the authors to submit papers on the topics detailed below.


– Analysis and interpretation of graphical documents, such as: Engineering drawings, floor plans, mathematical expressions, comics, maps, music scores, patents, diagrams, charts, tables, etc.
– Recognition of graphic elements, such as symbols, logos, stamps, drop caps, drawings, etc.
– Identification and localization of graphical mark-ups and annotations in written documents.
– Raster-to-vector techniques.
– Graphics-based information retrieval.
– Graphics recognition in Comics.
– 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.
– 3D models from multiple 2D 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.

3) Competitions of ICDAR 2023

Nineteen competitions are now up and running! Please find the list on ICDAR 2023 Competitions webpage and below to visit their websites, discover proposed tasks, datasets and participation deadlines.


Born Digital Video Text QA (BDVT-QA)

Detecting Tampered Text in Images (DTT)

Detection & Classification of Writing Activity in Air

Detection and Recognition of Greek Letters on Papyri
This competition investigates the performance of glyph detection and recognition on a very challenging type of historical document: Greek papyri. The detection and recognition of Greek letters on papyri is a preliminary step for computational analysis of handwriting that can lead to major steps forward in our understanding of this major source of information on Antiquity. It can be done manually by trained papyrologists. It is however a time-consuming task that would need automatising. We provide two different tasks: localization and classification or classification only.The document images are provided by several institutions and are representative of the diversity of book hands on papyri (a millennium time span, various script styles, provenance, states of preservation, means of digitization and resolution).

Document Information Localization and Extraction (DocILE)

Document UnderstanDing of Everything (DUDE) 😎
The ICDAR 2023 competition on Document Understanding of Everything (DUDE) proposes a new dataset for benchmarking Document Understanding systems under real-world settings that have been previously overlooked. In contrast to previous datasets, we extensively source multi-domain, multi-purpose, and multi-page documents of various types, origins, and dates. Importantly, we bridge the yet unaddressed gap between Document Layout Analysis and Question Answering paradigms by introducing complex layout-navigating questions and unique problems that often demand advanced information processing or multi-step reasoning. Finally, the multi-phased evaluation protocol also assesses the few-shot capabilities of models by testing their generalization power to previously unseen questions and domains, a condition essential to business use cases prevailing in the field. Submission deadline: 15 March 2023 AoE.

4) Workshops of ICDAR 2023

Nine workshops will be held in conjunction with ICDAR2023. Here is a list of their websites for more information and important dates.

Automatically Domain-Adapted and Personalized Document Analysis (ADAPDA)

  • This workshop aims at gathering expertise and novel ideas for personalized Document Analysis tasks (training and adaptation strategies of writer, language, and visual-specific models, new benchmarks, and data collection strategies), both on-line and off-line, with attention to privacy-preserving solutions.

Camera-Based Document Analysis and Recognition – 10th edition (CBDAR 2023)

  • The ICDAR 2023 Workshop on Camera-Based Document Analysis and Recognition (CBDAR 2023) will be the successor of the previous nine CBDAR workshops. The CBDAR series has a special focus on the analysis of camera captured documents and text. CBDAR is a forum for presenting up-to-date research, sharing experiences, and fomenting discussions on future directions in camera based document analysis.

Computational Document Forensics – 4th edition (IWCDF)

  • The Fourth International Workshop on Computational Document Forensics (IWCDF 2023) aims at presenting the most recent theoretical and practical advances related to digital document forgery while fostering discussions between academy and industry.

Computational Paleography – 2nd edition (IWCP)

  • The goal of this workshop is to bridge the gap between the different research fields analyzing handwritten scripts in ancient artifacts. It is primarily targeted at computer scientists, natural scientists, and humanists involved in the study of ancient writing systems and their materials, but it is not limited to these groups. By promoting discussion among these three communities, the workshop aims to encourage future interdisciplinary collaborations that will address current research questions about ancient manuscripts.

Graphics Recognition – 15th edition (GREC 2023)

  • GREC 2023 will 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 sub-field of document image analysis that deals with graphical entities in engineering drawings, comics, musical scores, sketches, maps, architectural plans, mathematical notation, tables, diagrams, etc.

Historical Document Imaging and Processing – 7th edition (HIP’23)

  • The 7th International Workshop on Historical Document Imaging and Processing (HIP’23) will bring together researchers from various fields working on document image acquisition, restoration, analysis, indexing, and retrieval to make these documents accessible in digital libraries. It is the seventh satellite workshop of ICDAR dedicated to this topic, following HIP’11 in Beijing, HIP’13 in Washington, HIP’15 in Nancy, HIP’17 in Kyoto and HIP’19 in Sydney and HIP’21 in Lausanne (hybrid) that were a significant success with strong participation. HIP aims to provide the researchers with a forum that is complementary and synergetic to the main sessions at ICDAR on document analysis and recognition.

Machine Learning – 4th edition (WML)

  • Since 2010, the year of initiation of the annual ImageNet Competition where research teams submit programs that classify and detect objects, machine learning has gained significant popularity. In the present age, Machine learning, in particular deep learning, is incredibly powerful to make predictions based on large amounts of available data. There are many applications of machine learning in Computer vision, pattern recognition including Document analysis, Medical image analysis etc. In order to facilitate innovative collaboration and engagement between document analysis community and other research communities like computer vision and images analysis etc. here we plan to organize this workshop of Machine learning.

Machine Vision and NLP for Document Analysis – 1st edition (VINALDO)

  • The first edition of the machine VIsion and NAtural Language processing for DOcument analysis (VINALDO) workshop comes as an extension of the GLESDO workshop, where we encourage the description of novel problems or applications for document analysis in the area of information retrieval that has emerged in recent years. We also encourage works that include NLP tools for extracted text, such as language models and Transforms. Finally, we also encourage works that develop new scanned document datasets for novel applications.

Scaling-up Document Image Understanding (ScalDOC)

  • Document Analysis has long suffered from both a fragmented landscape of task-specific datasets and a strong focus on narrow-focused information extraction and document conversion tasks. The Scaling-up document Image understanding workshop aims to open the discussion on possible ways for the community to align data preparation efforts and define large-scale (grand) challenges that drive progress in the field.. This is meant to be one of a series of such events to be organized on our scientific forums in the near future. The aspiration is to set the seed for an initiative to create our own community’s document-oriented “ImageNet”, over which multiple long-term grand challenges can be defined.
