CALL FOR PARTICIPATION

ICDAR 2013 Recognition of Handwritten Historical Texts (RHHT) Competition
http://users.dsic.upv.es/~cmartine/research/icdar2013-rhht.html

The "ICDAR 2013 Recognition of Handwritten Historical Texts (RHHT)"
competition is organised in the framework of the ICDAR 2013 competitions
by the PRHLT group. Its goal is to bring together the different
researchers working on off-line handwritten text recognition (HTR) and
let them work on the specific application of off-line HTR techniques to
historical texts, in order to provide them a suitable benchmark to compare
their techniques. In this competition, the recognition of a database of
historical handwritten text is proposed. The database corresponds to a
manuscript written in Spanish during the 16th century by a single writer.

DESCRIPTION AND GOALS

The participant systems must try to obtain the most accurate recognition
results of the test partition. The available data for achieving this task
will consist of:

- Image for each line of the training, validation, and test sets (see 
example below)
- Corresponding transcriptions for each line (only for training and 
validation sets)

Training partition is about 10,000 lines, whereas validation and test
partitions are about 5,000 lines each. An extra test partition of a
similar text, but from a different database, may be provided to check the
robustness of the systems against small changes in language and
handwritting style. A baseline system based on HTK and SRILM is provided,
along with a set of scripts that performs a baseline training and test
experiment. 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 using:

- different feature extraction techniques
- different recognition systems
- different types of models
- ...

The only restriction will be related to the final training data, that must 
pertain to the training and validation sets provided by the organisers.

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 differences 
between the submitted system and the baseline system. The final goal is to 
analyse the different proposals of the participants.

EVALUATION MODALITIES

The evaluation will be performed on the final result of the whole system 
(from preprocess to recognition). The evaluation metric is based on final 
word recognition, and Word Error Rate (WER) will be used to determine the 
performance of the systems. The winner will be the one that obtain the 
less WER on the test set. A web-based platform will be available for the 
participants to check their validation and test results.

The description of the methods and the evaluation scores will be presented 
during a dedicated ICDAR 2013 session. A report on the competition will be 
published in the ICDAR 2013 conference proceedings. Participants on this 
contest are not obliged to attend the ICDAR 2013 conference, although 
their presence in the presentation the evaluation and the posterior 
discusion will be very much appreciated.

INSCRIPTION AND ACCESS TO DATA

To inscribe in this contest send an e-mail to 
cmartine_AT_dsic_DOT_upv_DOT_es with the subject "ICDAR 2013 RHHT 
competition inscription". In the message you must provide the following 
data:
