Conference Title: 2015 15th International Conference on Intelligent Systems Design and Applications (ISDA) Conference Start Date: 2015, Dec. 14 Conference End Date: 2015, Dec. 16 Conference Location: Marrakech, Morocco In this paper a new approach to video event detection is presented. This approach is based on HOG/HOF features optimized by an auto-associative neural network models for feature reduction and an incremental SVM model for event classification. This auto-associative neural network models are frequently used to reduce the size of feature vectors. In our approach, each event is modeled by a set of states, and each state is represented by a learning model containing a positive class (event) and a negative class (non-event). Experiments on real video sequences have shown encouraging results.
