Identification de scripteurs pour l’écriture arabe par une approche locale
 La plupart des travaux de recherche dans le domaine de l'identification de scripteurs se sont orientés vers des documents écrits en script latin et peu d’études ont été effectuées sur des documents en arabe. Dans cet article, nous nous intéressons à l’identification hors-ligne de scripteurs utilisant l’écriture arabe. Nous proposons une approche locale en mode dépendant du texte où on cherche les formes invariantes et propres à l’écriture de chaque scripteur. Ces formes sont extraites par un découpage de l’écriture suivi d’une classification des formes obtenues qui sont ensuite organisées dans une base de référence pour permettre d’identifier l’auteur d’un document inconnu dans un processus de Pattern Matching. Les résultats obtenus sont de l’ordre de 93.33% en Top 1 et de 100% en Top 2 sur une base de 30 scripteurs. Mots clés : Ecriture arabe manuscrite, Identification de scripteur, Imagettes, Invariants du scripteur, Mode dépendant du texte, Pattern matching

ICFHR2016 competition on multi-script writer demographics classification using "qUWI" database
This competition is aimed at classification of writer demographics from offline handwritten documents using the QUWI database. QUWI is a bilingual database comprising writing samples of same individuals in Arabic and English. This allows evaluating the performance of different systems in a more challenging multi-script environment. This paper presents the details of the competition tasks, the datasets used in each of the tasks, a brief description of the participating systems, experimental protocol and evaluation criteria and finally the overall rankings of the participants.This work was made possible using grants from the Algerian Ministry of Higher Education and Scientific Research through CNEPRU project No. B?01120110084 as well as the Qatar National Research Fund through National Priority Research Program (NPRP) project No. NPRP7-442-1-082.Scopu

ICDAR2015 competition on Multi-script Writer Identification and Gender Classification using 'QUWI' Database
This competition targets writer identification and gender classification from offline handwritten documents using the QUWI database. The most interesting aspect of the competition is the use of a dataset with writing samples of the same individual in Arabic as well as English. The competition not only allows an objective comparison of different systems but also permits to investigate the performance of traditional script-dependent systems in a multi-script experimental setup. This paper describes the competition details including the competition tasks, the database employed, the methods used by the participating systems, evaluation and ranking criteria and the overall rankings of the participants. The competition received a total of 13 submissions from 8 different institutions. Writer identification tasks received 5 while the gender classification tasks received 8 submissions.Scopu
