This work describes a number of experiments aiming to assess the use of spectrogram to detect North Atlantic right whale calls. For this purpose, spectrograms are generated from the audio signal and then, Local Binary Pattern textural features are taken from the spectrogram images, once texture is the main visual content found in this kind of image. Following, these features are sent to a Support...
In this work we assesses the music genre classification using spectrograms taken from the original signal, percussive content signal, and harmonic content signal. The rationale behind this is that classifiers obtained from this three different representation of the signal may present some complementarity to each other. By this way, one can improve the recognition rates already obtained in previous...
