Text detection and recognition in a natural environment is a key component of many applications, ranging from business card digitization to shop indexation in a street. This new competition aims at assessing the ability of state of the art methods to detect and recognize multi-lingual text. This situation is encountered in modern cities where multiple cultures live and communicate together, where users see various scripts and languages in a way which prevent using much a priori knowledge. Multi-lingual text also poses a problem when analyzing streams of contents gathered on the Internet.
To register in this MLT-challenge of the RRC competition 2019, please do:
1) Register to the RRC portal as a user (if you are not already a registered user), this will allow you to access the "downloads"
2) Send an email to n[dot]nayef[at]gmail[dot]com with the title "Participation in the RRC-MLT-2019 challenge"
This registration process does not oblige you to participate or submit results, it is an expression of interest. You can participate in one or more tasks of the challenge. It is not obligatory to participate in all the tasks.
Process of Results Submission
27th May 2019: deadline for the submitting the 1) participants information (names/teams and affiliations), 2) methods descriptions for the task(s) in which you are participating and 3) initial results* (see below)
3rd June 2019: submission of the final results (you are able to update the results which you submit to us till 3rd June, for example if you tune more etc.). It is preferable if you submit earlier, and in this case, please notify us which one is your final submission.
* initial results: same format and completeness of the final results, but only the final results will appear in the MLT-2019 challenge results, and the initial results may be removed after 3rd June.
Motivation and relevance to ICDAR community
In this proposed competition we try to answer the question whether text detection and recognition methods (whether deep learning-based or otherwise) could handle different scripts/languages without fundamental changes in the used algorithms/techniques, or do we really need script-specific methods ?. The ultimate goal of robust reading is be able to read the text which appears in any captured image despite image source (type), image quality, text script or any other difficulties. Many research works have been devoted to solve this problem. The previous editions of RRC competitions and other works, have provided useful datasets to help researchers tackle each of those problems in order to robustly read text in natural scene images. In this competition, we extend state-of-the-art work further by tackling the problem of multi-lingual text detection, recognition and script identification. In other words, methods should be script-robust.
Despite the available datasets related to scene text detection or to script identification, our proposed dataset offers interesting novel aspects. The dataset is composed of complete scene images which come from 10 languages representing 7 different scripts. It combines text detection and recognition with script identification, and contains much more images than related datasets. The number of images per script is equal. This makes it a useful benchmark for the task of multi-lingual scene text detection. The considered languages are the following: Chinese, Japanese, Korean, English, French, Arabic, Italian, German, Bangla and Hindi (Devanagari).
Such dataset is the natural extension of the RRC series, with more scripts and more images while only focusing on intentional (or focused) text. It addresses the needs of the community for improved and robust scene text detection. The target audience of this dataset is obviously not only the ICDAR community, but also the computer vision community. In both communities, researchers work on analyzing scenes, scene text detection and recognition, quality of text images and script identification.
The datasets available in the literature for scene text detection are mostly not multilingual. The datasets which contain multi-script text are either built for Indian scripts only, or they contain a small number of scripts (2 - 4) with a relatively small number of images. Moreover, datasets that have been created for the tasks of script identification (classification) are composed of cropped text word images.
