IAPR TC11 is concerned with the theory and applications of Reading Systems. We seek to study and develop systems that recognize character content and structure in handwritten and typeset documents, images, and video.


Research Areas. IAPR's Technical Committee No. 11 (TC11) is concerned with work in document image processing, Optical Character Recognition (OCR), handwriting recognition, and more generally the analysis and recognition of information in documents. For a list of research areas of interest to TC11, please click [ here ]. These topics cover both recognition of printed texts as well as recognition of handwritten material, both off-line (from images) and on-line (from pen-and touch-based computing devices). Analysis of electronic documents such as web pages and PDF files is also of interest to TC11.

These topics cover all levels of document processing, starting with image or planar coordinates obtained from sensors, through image and signal-processing stages, feature extraction and selection, and algorithms used to segment, classify and parse document contents. Commonly, these algorithms involve some form of statistical and/or syntactic pattern recognition, as well as machine learning techniques.

Reading System Applications. Applications include digital libraries, pen-based computing, check and mail reading, signature verification, web mining and content repurposing, web security using human interactive proofs, textual content analysis in videos, and historical document preservation and archiving.

Logo. The current IAPR TC11 Logo was designed by Eloisa Alquati.

The ICDAR Advisory Board is seeking proposals to host the 16th International Conference on Document Analysis and Recognition, to be held in 2021 (ICDAR2021). ICDAR is the premier IAPR event in the field of Document Analysis and Recognition with 300 to 500 participants. The aim of this conference is to bring together international experts to share their experiences and to promote research and development in all areas of Document Analysis and Recognition.

Any consortium interested in making a proposal to host an ICDAR should first familiarise themselves with the "Guidelines for Organizing and Bidding to Host ICDAR" document which is available on the TC10 and TC11 websites ( http://iapr-tc10.univ-lr.fr and http://www.iapr-tc11.org respectively).

A link to the most current version of the guidelines appears below. Small updates in the guidelines are expected during the next few weeks, so please check on the Web site of TC11 for the latest version.

The submission of a bid implies full agreement with the rules and procedures outlined in that document. The submitted proposal must define clearly the items specified in the guidelines (Section 5.2).

It has been the tradition that the location of ICDAR conferences follows a rotating schedule among different continents. Hence, proposals from America are encouraged. However, high quality bids from other locations, for example, from countries where we have had no ICDAR before, will also be considered. Proposals will be examined by the ICDAR Advisory Board.

Proposals should be emailed to Dr. Dimosthenis Karatzas at [dimos@cvc.uab.es ] and Dr. Bart Lamiroy at [bart.lamiroy@loria.fr ] by June 15, 2017.

ICDAR Advisory Board

  • Dimosthenis Karatzas (Chair, TC11)
  • Bart Lamiroy (Chair, TC10)
  • Dan Lopresti (Chair, IAPR C&M)
  • Jean-marc Ogier
  • Josep Llados
  • Simone Marinai
  • Cheng-Lin Liu


The TC11 of the IAPR has spawned a number of lively activities in the area of pattern recognition: a journal, three conference series, maintaining collections of data sets and software, numerous workshops, and a project for benchmarking on-line handwriting recognizers.

TC11 maintains a collection of datasets and software packages, along with projects and forums available from the links below.

TC11 Summer School

Part of the mission of TC11 is to promote high quality educational activities related to Reading Systems and Graphics Recognition. The "TC10/TC11 Summer School" is intended to become the prime educational activity of IAPR TC11 (Reading Systems) and TC10 (Graphics Recognition). The Summer School is meant to be a training activity where participants are exposed to the latest trends and techniques of Reading Systems and Graphics Recognition.

TC10/TC11 Summer Schools will be organised in a bi-annual basis on even years, interleaved with ICDAR conferences which are organised on odd years. A call for bids to host the TC10 / TC11 Summer School is distributed by TC10 and TC11 about six months before the ICDAR conference of the year before the School should takes place.

Any consortium interested in making a proposal to host the TC10/TC11 Summer School must proceed according to the Guidelines for Organising and Bidding to Host the TC10 / TC11 Summer School.
