Title

Ermittlung von begrifflichen Beschreibungen von Geschehen in Straßenverkehrsszenen mit Hilfe unscharfer Mengen

Abstract
This contribution addresses the problem to extract a conceptual description of moving vehicles in image sequences from traffic scenes recorded by a stationary camera. Due to considerable improvements in image sequence analysis more densely sampled -25 Hz instead of 1.25 Hz - trajectories are now available. In order to associate motion verbs and verb phrases to these trajectory segments, a complete rework of existing methods was necessary. Fuzzy sets are used to represent the connections between trajectory attributes and verbs.
