Abstract

In this paper we present an approach for acoustic scene classification, which aggregates spectral and temporal features. We do this by proposing the first use of the variable-Q transform (VQT) to generate the time-frequency representation for acoustic scene classification. The VQT provides finer control over the resolution compared to the constant-Q transform (CQT) or STFT and can be tuned to better capture acoustic scene information. We then adopt a variant of the local binary pattern (LBP), the Adjacent Evaluation Completed LBP (AECLBP), which is better suited to extracting features from acoustic time-frequency images. Our results yield a 5.2% improvement on the DCASE 2016 dataset compared to the application of standard CQT with LBP. Fusing our proposed AECLBP with HOG features we achieve a classification accuracy of 85.5% which outperforms one of the top performing systems.
