Generalized cross-correlation based noise robust abnormal acoustic event localization utilizing non-negative matrix factorization

In this paper, robust sound source localization for surveillance system is presented. In particular, we propose an algorithm for abnormal acoustic event localization using non-negative matrix factorization based frequency bin weighting. Based on the abnormal acoustic event localization experiments in real acoustic environment, the proposed algorithm´s excellent strength is validated in terms of representative performance measures compared to the conventional method.
