Résumé :

Bayesian (also called Belief) Networks (BN) is a powerful knowledge representation and reasoningmechanism. Based on probability theory involving a graphical structure and random variables, BN iswidely used for classification tasks and in this paper, BN is used as a class discrimination tool for a set ofweld defects radiographic images using suitable attributes based on invariant geometric descriptors. Testsare performed on a database of few hundred elements where the results are outstanding and verypromising, since they outperform those given by powerful SVM classifiers.
