Improved spectral dynamic features extracted from audio data for classification of marine vessels

Murillo de Brito Santos,
Rogério de Moraes Calazan

Abstract: Underwater sound classification presents a unique challenge due to the complex propagation characteristics of sound in water, including absorption, scattering, and refraction. These complexities can distort and alter spectral features, hindering the effectiveness of traditional feature extraction methods for vessel classification. To address this challenge, this study proposes a novel feature extraction method that combines Mel-frequency cepstral coefficients (MFCCs) with a spectral dynamic feature (SDF) vecto… Show more
