Mesure de la netteté sur une image seule dans des documents anciens

This article presents some way to do quality control after digitization, specially out of focus problem. We will enumerate different point of view to analyse and to estimate this information. To validate descriptors, we suggest to blur any picture and to compute blur estimation in order to evaluate precision. After that, we propose to combinate descriptors by machine learning. MOTS-CLÉS : docum...

Sur une Généralisation des Coefficients Binomiaux

We prove a recent conjecture of Lassalle about positivity and integrality of coefficients in some polynomial expansions. We also give a combinatorial interpretation of those numbers. Finally, we show that this question is closely related to the fundamental problem of calculating the linearization coefficients for binomial coefficients.

Choix d'une mesure d'association pour une extension de requête contôlée : la question de l'orientation de la mesure

This paper describes a comparative study of association measures in the context of thesaurus construction. The study deals more particularly with the orientation of the association measure. Several solutions are identified and tested in an adaptive filtering task. In this task, the thesaurus is used to select the terms to take into account in the learning step. The results obtained on the OSHUM...
