IAPR TC11 is the International Association for Pattern Recognition (IAPR) Technical Committee Number 11. 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mining and content repurposing, web security using human interactive proofs, textual content analysis in videos, and historical document preservation and archiving.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.

DAS 2018 Awards Congratulations to the DAS award winners, Daniel Stromer (Best Student Paper), and Praveen Krishnan, Katrik Dutta, and C. V. Jawahar (Nakano Best Paper Award) <https://das2018.cvl.tuwien.ac.at/en>


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

New: [| 2018 School in La Rochelle - Call for Participation ]

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.
