Semantic queries involving image understanding aspects require the exploitation of multiple clues, namely the (inter-)relations between objects and events across multiple images, the situational context, and the application context. A prominent example for such queries is the identification of individuals in video sequences. Straightforward face recognition approaches require a model of the persons in question and tend to fail in ill conditioned environments. Therefore, an alternative approach is to involve contextual conditions of observations in order to determine the role a person plays in the current context. Due to the strong relation between roles, persons and their identities, knowing either often allows inferring about the other.
