Dining Activity Analysis Using a Hidden Markov Model
We describe an algorithm for dining activity analysis in a nursing home. Based on several features, including motion vectors and distance between moving regions in the subspace of...

Probability distribution of the switching intervals in chaotic pulse streams-a comparative study
In switched dynamic system the continuous phase ow is accompanied by a stream of switching events. If the system exhibits chaotic behavior this event stream can be used for gener...

Group Activity Recognition Based on ARMA Shape Sequence Modeling
In this paper, we propose a system identification approach for group activity recognition in traffic surveillance. Statistical shape theory is used to extract features, and then...
