Dear members,

At the “2nd Future of Document Analysis and Recognition Workshop” (at ICDAR 2019), we discussed the future of our community. During 2020, we set a Task Force to continue the discussions towards the definition of a strategic plan for the document analysis and recognition community. We involved the TC10/TC11 chairs/vice-chairs and some of the previous/future organizers of our events (conferences, workshops, summer schools).

Detailed information of the activity (including kialo discussions, forms for feedback, etc.) is available at the website: https://sites.google.com/view/darstrategy

A key proposal of the Task Force was to decide whether we want an annual ICDAR conference. All members in the community were invited to vote and give their opinion on the opportunity to have an annual high quality ICDAR conference. We appreciate your participation in the survey and are glad to announce that the majority (~76%) of the DAR community opted for holding ICDAR annually.

A call for bids to host ICDAR 2024 will be opened soon. Looking forward to your active support in organizing ICDAR annually.

Faisal Shafait, TC11 Chair

ICDAR 2021: Keynote Speakers

Speaker 1: Prem Natarajan

OCR: A Journey through Advances in the Science, Engineering, and Productization of AI/ML

From the very early years of AI, the problem of optical character recognition (OCR) has captured the imagination of researchers; Selfridge and Neisser presented an approach for OCR of hand printed characters in 1960. During last three decades, optical character recognition (OCR) technology for machine printed and handwritten text has evolved in significant ways – from script-specific techniques to script-independent methodologies, and from segmentation-based techniques to hidden Markov models to deep learning. In my talk, I will present my perspective on that evolution and it’s interplay with concomitant advances in speech recognition, natural language processing, and computer vision. The presentation will include a discussion of some practical, even if off the beaten path, applications of OCR technology, including work done in partnership with the census bureau in applying a deep learning based OCR framework to census forms. I will also share my views on some of the most interesting open problems in the field of OCR and document processing. The presentation will conclude with a few comments about one of my current areas of research interests – fairness in AI and machine learning.

Speaker 2: Beáta Megyesi

Cracking Ciphers with “AI-in-the-loop”: Transcription and Decryption in a Cross-Disciplinary Field

Accurate transcription of hand-written texts in images is indispensable in many research areas in digital humanities. Manual transcription is error-prone, time-consuming, and expensive to produce. Historical texts with their specific textual qualities require expert knowledge and trained eyes. During the past years, image processing applied to hand-written historical text documents to provide transcription output has been shown great opportunities, but also challenges for users. How can users without knowledge in AI in general and HTR in particular transcribe hand-written documents efficiently with ”AI-in-the- loop”? In my talk, I will focus on encrypted manuscripts from Early Modern times with various symbols systems, hand-writing styles, and languages. The point of departure is the DECRYPT project, aiming at the creation of resources and tools for historical cryptology by bringing the expertise of various disciplines together for collecting images of ciphers and keys, to transcribe them, and to decrypt and contextualize those. I will give an overview of the project, the methods we use to solve various problems from transcription to decryption including historical corpora and natural language processing methods.

ICDAR 2021: COVID Situation

Swiss COVID Regulations

The following websites are regularly updated by the government:

What does it mean for ICDAR?

The current COVID situation in Switzerland allows to hold ICDAR 2021 in person. A hybrid mode is setup with both on-site and online participants. It is recommended to register for on-site participation if you plan to attend the conference in person. Should it become necessary to limit on-site participation to scientific and/or social events, the date of payment of the registration fee will be taken into account, following the “first come, first serve” principle. If travel is not possible due to COVID-related restrictions, a downgrade to online participation will be applied, refunding the difference in the registration fees.

Current COVID measures envisaged for ICDAR 2021

Wearing masks when indoors. We are observing the evolution of the COVID certificate (fully vaccinated, recovered from COVID, or tested negativ) but do not impose it for the conference at the moment.
