| Özet: | This paper presents a method for automatic bird song recognition. This method is based on the principal components analysis (PCA) of bird chant’s spectrograms, by using eigenfaces. For the database confection, we used a detection method for acoustic activity applying a moving average filter. We assembled a database of three chants of different birds: Formicivora Grisea, Harpia Harpyja and Reinita Protonotaria. The obtained results show the effectivity of the proposed method, obtaining a recognition rate of 100%. |
