07 - Définition et évaluation d'une famille de représentations pour la vérification hors-ligne des signatures

In a real situation, the choice of the best representation for the implementation of a signature verification system able to cope with all types of handwriting is a very difficult task. This study is original in that the design of the integrated classifiers is based on a large number of individual classifiers (or signature representations) in an attempt to overcome in some way the need for feature selection. In fact, the cooperation of a large number of classifiers is justified only if the cost of individual classifiers is low enough . This is why the extended shadow code (ESC) used as a class of shape factors tailor-made for the signature verification problem seems a good choice for the design of integrated classifiers E(x) .
