(unavailable)
We describe a system which, building on previous team action recognition systems, performs a more in-depth analysis of an ongoing team action executed by a group of embodied agents. The system relies on team action states with human understandable semantics, estimates the current state and is able to make predictions or identify fringe cases such as incomplete or incorrectly executed team actions. The representation of the team action relies on a dynamic Bayesian network (DBN). We perform reasoning over the DBN using a sampling-importance-resampling particle filter. As a methodological illustration, we describe the process of model building for the bounding overwatch team action. We experimentally test our approach using data acquired from video recordings, and measure the systems' ability to recognize a team action and to estimate the current state.
