On time-frequency representations for underwater acoustic signal
P Courmontagne, S Ouelha, F Chaillan - 2012 Oceans, 2012 - ieeexplore.ieee.org
In order to develop a new human perception inspired process useful for underwater acoustic
signal processing, the purpose of this paper is to present a new human physiology based
time-frequency representation. This method is based on the use of the Mel filters, classicaly
used for the voice recognition. Several experimentations on real underwater signals are
presented and discussed.
