Abstract
In this paper, we present an event detection system evaluated in TRECVid 2013. We investigated a generic statistical approach with spatio-temporal features applied to the event “Object Put”. This approach is based on local spatial constrained spatio-temporal descriptors, named as SC-MoSIFT. We extended the spatio-temporal features, MoSIFT, by relative position to camera. We also statistic the frequency and the location of each event occurs, and use selective hot region to construct spatial Bag-of-Feature. Non-linear SVM is exploited to train classifier for each event on each camera. In the limited experimental time, we adopted experiments and got comparable results to show the effectiveness of our approach.
