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.
