Smartphones for automatic shad counting
Résumé
Smartphones are used here to develop a signal processing application. An acoustic signal analysis method is proposed for estimating the population of migrating shad (Alosa fallax rhodanensis) in rivers. The method consists in detecting sounds of splashes produced by shads during spawning acts. It is based on short-term spectral analysis, combined with GMM classification. The results obtained are very promising, and will be used to deploy automatic counting field devices.
