International audienceIn diesem Artikel stellen wir Methoden zur Detektion und Klassifikation von Ereignissen in instationären Signalen vor, welche gut zur Verarbeitung von Uterus-EMG-Signalen geeignet sind. Zwei sequentielle Detektionsmethoden werden vorgestellt: die erste ist eindimensional und basiert auf einer AR-Modellierung, die zweite ist mehrdimensional und verwendet eine Zerlegung des Signals in unterschiedliche Skalen mittels der Wavelet-Transformation. Eine Verwerfung von Hypothesen wird unter Verwendung der AR-Koeffizienten oder einer aus den Skalen berechneten Varianz-Kovarianz-Matrix erzielt. Beide Methoden sind adaptiv und gestatten die Detektion von Ereignissen, ohne notwendigerweise zur Null-Hypothese H0 zurückzukehren. Die...
