Vision Algorithms: Behaviour Recognition
Scenario Representation
- Hierarchy of States, Events and Scenarios :
- State: situation describing a generic spatio-temporal property,
usually numerical, involving one or several actors on a time interval Ex
: « close», « walking», « seated»
- Event: change of states at two consecutive times
Ex : « enters», « stands up», « leaves »
- Scenario: set of states and/or events satisfying specific temporal
constraints. It corresponds to a long term, symbolic, application
dependent activity. A behaviour is a scenario defined by the users Ex :
« fighting», « vandalism»
