Scenario, event-driven, activity recognition, formal methods
Scenarios play an important role in various computer domains. Scenarios represent activities to be described and recognized (video understanding and video surveillance, air traffic control...). Designing reliable and efficient scenario recognition tools requires to rely on a formal model. Our target scenarios should support uncertainty on input events (coming from sensors), alternative sub scenarios and different constraints (about timing, duration, ordering...). Therefore we need a model that meets all these requirements. Moreover, in order to be tracktable, the model should be hierarchical to be able to deal with smaller sub models.
The intership objective is thus first to conduct a bibliographic study about modeling techniques (e.g., stochastic grammars, hidden Markov models, probabilistic automata) and to select or design a suitable model. Since our goal is scenario recognition, the second point is to study a scenario recognition algorithm relying on the choosen model.
