This paper presents a hierarchical approach for audio based event detection for surveillance. The proposed approach first classifies a given audio frame into vocal and nonvocal events, and then performs further classification into normal and excited events. We model the events using a Gaussian Mixture Model and optimize the parameters for four different audio features ZCR, LPC, LPCC and LFCC. Experiments have been performed to evaluate the effectiveness of the features for detecting various normal and the excited state human activities. The results show that the proposed top-down event detection approach works significantly better than the single level approach. © 2006 IEEE. | Source Title: | ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings | URI: | http://scholarbank.nus.edu.sg/handle/10635/41375 | ISBN: | 142440469X | ISSN: | 15206149 |
