Résumé

Cette étude porte sur l'application des filtres particulaires à deux problèmes d'extraction d'information en acoustique passive. La description concerne plus spécifiquement deux algorythmes ayant pour objectif l'extraction de contour des sifflements de dauphins et la localisation en trois dimensions d'animaux vocalisant à partir d'un jeu de capteurs répartis localement. L'objectif de ce travail est de mettre en lumière le potentiel des filtres particulaires pour l'analyse de signaux bioacoustiques. Parmi les filtres particulaires, l'accent est mis dans cette étude sur forme particulière de filtre: le filtre à rééchantillonnage d'importance séquentiel.
