Réallocation du spectrogramme pour la détection de frontières de motifs temps-fréquence
Résumé
In this paper, we propose a boundary detection of time-frequency patterns of the spectrogram, based on the reassignment method. The reassignment vector is used here not to modify the time-frequency representation, but only as a source of information about the spectral structure of the signal. This approach focused on the boundaries extends the use of the reassignment principle to wide band signals.
