Zur Strukturierung eines Bildfolgen-Auswertungssystems : Themenheft : Sonderforschungsbereich 314 - Künstliche Intelligenz - Wissensbasierte Systeme

Evaluation of image sequences denotes a process which transforms a digitized image sequence into a description of the depicted scene and of its temporal evolution. In a hierarchy of levels of abstraction at which such a description is formulated, each level can be mapped onto a component of a system computing the desired abstraction. As an example, the structure of a system will be discussed which automatically extracts trajectories of vehicles from video sequences of street traffic scenes and describes them at the level of motion verbs. With increasing experience, this system as well as the knowledge used by each component can be structured better. This in turn facilitates to scrutinize the effect of each component on the entire system in order to improve the overall system performance.
