SBGM: Conciliation et mesures de conflits

We propose to define new conciliation operators. Those operators are based on an iterative selection/weakening process of the beliefs/goals of the agents, until a consensus (agreement) is found between the agents. To define a particular operator, it just need to choose a choice function and a weakening function. In previous works the choice function was defined arbitrarily. We propose to take a...

Approche markovienne bidimensionnelle d'analyse et de reconnaissance de documents manuscrits

In this thesis, we present a general bidimensional markovian approach in theframework of handwritten document analysis and recognition. This approachcalled AMBRES (Bidimensional Markovian Approach for image Recognition andSegmentation) is based on Markov random elds, 2D dynamic programming anda bidimensional analysis of images.AMBRES has been successfully applied to a wi...

Détection et reconnaissance de texte dans les documents vidéos. Et leurs apports à la reconnaissance de personnes

This article presents the different steps used to recognize characters for multi-modal person recognition systems in video (ANR REPRE challenge). Text detection is achieved by a technique based on the text features (texture, color, contrast, geometry, temporal information, measure of accumulated gradients). The text recognition is then performed by the free software Google Tesseract. The method...

Reconnaissance et classification de lettrines à base des descripteurs de bas niveau et de représentation structurelle

This article tackles some important issues relating to the analysis of a particular case of complex ancient graphic images, called “lettrines”, “drop caps” or “ornamental letters”. Our contribution focuses on proposing generic solutions for lettrine recognition and classification. Firstly, we propose a bottom-up segmentation method, based on auto-correlation features, ensuring the separation of...
