Anti-social behavior detection in audio-visual surveillance systems
Kuklyte, Jogile; Kelly, Philip; Ó Conaire, Ciarán; O'Connor, Noel E.; Xu, Li-Qun
In this paper we propose a general purpose framework for detection of unusual events. The proposed system is based on the unsupervised method for unusual scene detection in web{cam images that was introduced in [1]. We extend their algorithm to accommodate data from different modalities and introduce the concept of time-space blocks. In addition, we evaluate early and late fusion techniques for our audio-visual data features. The experimental results on 192 hours of data show that data fusion of audio and video outperforms using a single modality.
