Normalized power spectrum (left) and corresponding energy ratio map (right) for (a) BWW (n = 279), (b) RD (n = 429), and (c) SPW (n = 389). Vertical bars in the normalized power spectra represent standard deviation for corresponding energy in frequency bin.
ERMA combined non-target species map for RD and SPW.
ERMA discrimination map for BBW with consideration of two additional odontocete species, RD and SPW.
ROC curves for ERMA-based detector for BBW and SNR classes 5–10 dB, 10–15 dB, and 15–20 dB.
Overview of the data set used to train and test ERMA. It comprises a subsample of the data set for the Third International Workshop on the Detection, Classification and Localization of Marine Mammals Using Passive Acoustics, Boston, MA, USA; published online at www.MobySound.org. All recordings are sampled at 96 kHz and 16-bit resolution.
