A novel approach for the detection of vehicles on freeways by real-time vision

As part of a system allowing the recognition of an entire road traffic situation in real time a detector for other vehicles following the ego vehicle has been developed. It generates a distance-invariant object representation to overcome the difficulties caused by variations in the visual appearance of objects when they are seen from different distances. The vehicle detector was implemented on different vision systems and successfully tested in a variety of real-world scenes.
