15 p, 1.3 MB Combining Model-based and Discriminative Approaches in a Modular Two-stage Classification System : application to Isolated Handwritten Digit Recognition / Milgram, Jonathan (Université du Québec. École de Technologie Supérieure) ; Sabourin, Robert (Université du Québec. École de Technologie Supérieure) ; Cheriet, Mohamed (Université du Québec. École de Technologie Supérieure)
The motivation of this work is based on two key observations. First, the classification algorithms can be separated into two main categories: discriminative and model-based approaches. Second, two types of patterns can generate problems: ambiguous patterns and outliers. [...]

14 p, 993.9 KB Contextual System of Symbol Structural Recognition based on an Object-Process Methodology / Delalandre, Mathieu (Université de Rouen. PSI Laboratory) ; Trupin, Eric (Université de Rouen. PSI Laboratory) ; Ogier, Jean-Marc (Université de La Rochelle. L3I Laboratory) ; Labiche, Jacques (Université de Rouen. PSI Laboratory)
We present in this paper a symbol recognition system for the graphic documents. This one is based on a contextual approach for symbol structural recognition exploiting an Object-Process Methodology. [...]

17 p, 580.7 KB Learning Model Structure from Data : an Application to On-Line Handwriting / Binsztok, Henri (Université Paris VI. LIP6) ; Artières, Thierry (Université Paris VI. LIP6)
We present a learning strategy for Hidden Markov Models that may be used to cluster handwriting sequences or to learn a character model by identifying its main writing styles. Our approach aims at learning both the structure and parameters of a Hidden Markov Model (HMM) from the data. [...]

11 p, 440.7 KB Frequent Graph Discovery : application to Line Drawing Document Images / Barbu, Eugen (Université de Rouen. Laboratoire PSI) ; Heroux, Pierre (Université de Rouen. Laboratoire PSI) ; Adam, Sebastien (Université de Rouen. Laboratoire PSI) ; Trupin, Eric (Université de Rouen. Laboratoire PSI)
In this paper a sequence of steps is applied to a graph representation of line drawings using concepts from data mining. This process finds frequent subgraphs and then association rules between these subgraphs. [...]

14 p, 173.7 KB A K Nearest Classifier design / Prudent, Y. (University and INSA of Rouen. PSI Laboratory) ; Ennaji, A. (University and INSA of Rouen. PSI Laboratory)
This paper presents a multi-classifier system design controlled by the topology of the learning data. Our work also introduces a training algorithm for an incremental self-organizing map (SOM). This SOM is used to distribute classification tasks to a set of classifiers. [...]

15 p, 188.7 KB Handwritten Document Analysis for Automatic Writer Recognition / Bensefia, Ameur (Université de Rouen. Laboratoire PSI) ; Paquet, Thierry (Université de Rouen. Laboratoire PSI) ; Heutte, Laurent (Université de Rouen. Laboratoire PSI)
In this paper, we show that both the writer identification and the writer verification tasks can be carried out using local features such as graphemes extracted from the segmentation of cursive handwriting. [...]

11 p, 816.2 KB Self-supervised adaptation for on-line script text recognition / Outdot, Loïc (Universit Pierre et Marie Curie) ; Prevost, Lionel (Universit Pierre et Marie Curie) ; Milgram, Maurice
We have recently developed in our lab a text recognizer for on-line texts written on a touch-terminal. We present in this paper several strategies to adapt this recognizer in a self-supervised way to a given writer and compare them to the supervised adaptation scheme. [...]

13 p, 327.4 KB Multiorder polygonal approximation of digital curves / Debled-Rennesson, Isabelle (LORIA-INRIA (Vandœuvre-les-Nancy, França)) ; Tabbone, Salvatore (LORIA-INRIA (Vandœuvre-les-Nancy, França)) ; Wendling, Laurent (LORIA-INRIA (Vandœuvre-les-Nancy, França))
In this paper, we propose a quick threshold-free algorithm, which computes the angular shape of a 2D object from the points of its contour. For that, we have extended the method defined in [4, 5] to a multiorder analysis. [...]
