The 22nd Document Recognition and Retrieval Conference is being held as part of the IS&T/SPIE Electronic Imaging Symposium taking place in San Francisco, California, USA at the Hilton San Francisco Union Square in the heart of town.
The Conference Chairs and Program Committee invite all researchers interested in document recognition and retrieval to attend for the presentation of original research papers and invited talks by Dan Klein of the University of California, Berkeley, and Brewster Kahle of the Internet Archive.
INVITED TALKS - Dan Klein, Feb.11: "Printing presses and polyphonic pianos: unsupervised transcription for documents and music". - Brewster Kahle, Feb.12: "The internet archive: challenges and solutions for large scale document repositories".
ICDAR 2015 Doctoral Consortium: Call for participation
In 2011 the Leadership Teams of TC-10 and TC-11 agreed to jointly organize the first Doctoral Consortium in conjunction with ICDAR 2011 which lead to a successor event that took place in conjunction with ICDAR 2013. Given the great success of these initial events the tradition of Doctoral Consortiums as satelite events to ICDAR conferences will be continued.
The goal of the ICDAR 2015 Doctoral Consortium is to create an opportunity for Ph.D. students to test their research ideas, present their current progress and future plans, and receive constructive criticism and insights related to their future work and career perspectives. A mentor (a senior researcher who is active in the field) will be assigned to each student to provide individual feedback. In addition, students will have the opportunity to present an overview of their research plan during a special poster session.
Participation in the ICDAR 2015 Doctoral Consortium will be be limited to 25 students. Prospective participants are encouraged to submit their application by May 15 (submission procedure to be announced). The Doctoral Consortium Chairs will then review all applications received. Preference will be given to students who are at a stage in their studies most likely to benefit (i.e., they have identified a research direction and published some initial results, but the thesis is not yet set in stone). As in previous years, the event will be organized such that the registration fees for participating students will be minimal. The ICDAR 2015 Doctoral Consortium will take place the day before the main conference, i.e., on August 23.
Important dates - Submission deadline: May 15 - Acceptance notification and Mentor assignment: May 31 - Final material due: July 10 - Doctoral Consortium: August 23
The 6th International Workshop on Camera Based Document Analysis and Recognition (CBDAR 2015) will be held in Gammarth, Tunisia, on August 22nd 2015 in conjunction with ICDAR 2015.
The pervasiveness and widespread availability of camera phones, hand-held digital still/video cameras and more recently wearable cameras have led the community to recognize camera captured images as a promising and growing field of research for document analysis and recognition. Document digitization techniques are gradually getting closer to camera based solutions, offering certain advantages (e.g. for scanning large scale or fragile documents), and presenting interesting new challenges and open problems which cannot be directly resolved by traditional techniques.
Building on the success of the previous five CBDAR workshops in 2005 (Seoul, Korea), 2007 (Curitiba, Brazil), 2009 (Barcelona, Spain), 2011 (Beijing, China), and Washington DC (USA), CBDAR 2015 will be held in Gammarth, Tunisia in conjunction with ICDAR 2015. The aim of the workshop is to provide a natural link between document image analysis and the wider computer vision community by attracting cutting edge research on the topic.
Topics of Interest - camera based acquisition of written information - restoration of camera captured documents (dewarping, deblurring, etc.) - image degradation models for camera captured characters/documents - document image quality analysis - character segmentation / recognition from scene images - layout analysis for camera captured documents - text in video - document image retrieval - devices and algorithms for camera-based document analysis and recognition - device constrained techniques and algorithms - performance evaluation and metrics - applications such as translation, reading text for the blind, etc - human-document interaction
Workshop Chairs - Dr Dimosthenis Karatzas (Computer Vision Centre - Spain) - Dr Faisal Shafait (University of Western Australia -Australia)
Workshop Format CBDAR is a 100% participation, one-day, single-track workshop featuring keynote talks, oral/poster presentations, a demo session, and a panel discussion.
Publications Electronic copies of the workshop proceedings containing all contributed papers will be distributed at the workshop. After the workshop, revised versions of selected papers will be published in Springer LNCS series as post-proceedings.

"Robust Reading" refers to the research area dealing with the interpretation of written communication in unconstrained settings. Robust Reading is at the meeting point between camera based document analysis and scene interpretation. The ICDAR Robust Reading Competition is organized around challenges selected to cover a wide range of real-world situations, which are in turn set up around different research tasks.
The ICDAR 2015 Robust Reading competition will build upon the success of the previous editions and will introduce two key changes. First, a new "end-to-end" task is introduced aiming at simultaneous word localisation and recognition in images and videos. Second, a Challenge on incidental text is introduced based on a new large dataset (in the thousands of images), the focus of this challenge is on text that appears in the scene without the user having taken any specific prior action to cause its appearance or improve its positioning / quality in the image.
Participation is welcome in any Task and Challenge in an open mode (submission of results over a provided test set).

ICDAR2015 Competition HTRtS: Handwritten Text Recognition on the tranScriptorium Dataset
The "ICDAR2015 Competition HTRtS: Handwritten Text Recognition on the tranScriptorium Dataset" competition is organised in the framework of the ICDAR 2015 competitions by the Pattern Recognition and Human Language Technologies research centre with the collaboration of the tranScriptorium partners. This contest aims to bring together researchers working on off-line Handwritten Text Recognition (HTR) and provide them a suitable benchmark to compare their techniques on the task of transcribing typical historical handwritten documents. The first edition of this contest HTRtS2014 was organised in the ICFHR 2014.
The proposed dataset consists of a series of documents from the Bentham collection, which has been prepared in the tranScriptorium project. This dataset includes manuscripts written by Jeremy Bentham (1748-1832) himself over a period of sixty years, as well as fair copies written by Bentham's secretarial staff. Handwriting in this collection is complex enough to challenge the HTR software: manuscripts written by secretarial staff will provide variety, while Bentham's manuscripts are often complicated by deletions, marginalia, interlineal additions and other features. The data used in this contest is closely related to the data used in the ICDAR2015 Competition on Keyword Spotting for Handwritten Documents (http://transcriptorium.eu/~icdar15kws/).
The dataset for this competition is composed of 796 pages; most of the pages consist of a single block with many difficulties for line detection and extraction (see page samples below). The dataset is divided into 3 batches for the competition: 2 batches for training (batch 1 and batch 2) and 1 batch for test (batch 3). The number of writers is unknown (see web pages for detail).
DESCRIPTION AND GOALS The systems entering this contest should try to obtain the most accurate recognition results in the test partition.
The available data for batch 1 will consist of: 1. The original images of all the training pages 2. The PAGE file corresponding to each page image. For each text line in this image, the PAGE file contains a bounding polygon and the corresponding correct transcript. 3. The preprocessed and extracted line images for all the lines of the training and validation sets in grayscale. 4. A sequence of feature vectors for each line. 5. The corresponding transcripts of each of these lines.
Items 1 and 2 are redundant with items 3 and 5 and are provided for those who wish to try improving results by using specific image preprocessing and line extraction tools. Item 4 is provided for those who do not wish to try improving results at pre-processing and feature extraction level.
The available data for the batch 2 will consist of: 1. The original images of all the training pages. 2. The PAGE file corresponding to each page image. The PAGE file contains the bounding polygon for the text regions, not for the line regions. 3. For the text regions, a separated file with the corresponding correct transcripts will be provided.
The test images (batch 3), with the transcript fields empty, will be eventually provided in the same (redundant) formats as first batch for evaluation purposes (see schedule below).
A baseline system based on HTK hidden Markov models and SRILM language modelling will be provided, including a set of scripts to perform a basic training and test experiment (using batch 1). The participants can use this baseline system as an initial approach to their own systems, where they will be allowed to improve this baseline by changing one or several of the following steps:
- page-level pre-processing and line extraction - line pre-processing and normalisation - feature extraction - recognition system and/or approach - types of character, lexical and/or language models - etc.
Several submissions per participant will be allowed and all the results will be considered when presenting the competition results. In each submission, the participant must provide a brief description of the characteristics of the submitted system, emphasising the main characteristics of the submitted system. The final goal is to analyse the different proposals of the participants.
EVALUATION MODALITIES The evaluation will be performed on the transcription results provided by each recognition system. The evaluation metric will be the Word Error Rate (WER) between the reference transcript and the transcript provided by the system from each line. The winner will be the system which obtains the least WER on the test set. A web-based platform will be available for the participants to check their test results.
Two tracks are planned in this competition: - Restricted track: in this track the participants can use only the data provided by the organisers for training and tuning their systems - Unrestricted track: in this track the participants can use any data of their choice
The baseline system will be prepared only for the restricted track. It is mandatory that the entrants participating in the "Unrestricted track" participate in the "Restricted track". The idea of this obligation is to be able to compare several systems in analogous training conditions.
