Résumé

Un problème de détection et reconnaissance des baleines noires, Eubaleana glacialis, en présence de bruit ambiant est étudié. Une solution proposée est basée sur une technique de test d’hypothèses en plusieurs étapes, impliquant le détecteur, des tests de spectrogramme et des algorithmes testant des vecteurs de traits. Les résultats des tests montrent que la technique proposée est capable de détecter plus de 80% des appels de contact détectés par les opérateurs humains et de produire environ 26 fausses alarmes par 24 h d’observation.
