In this article, a method is presented for detecting vehicles in image sequences without prior knowledge about the position of the road. A single camera placed in a moving vehicle provides image data. For the detection of midrange and distant vehicles, a combination of three clues is used: shadow, entropy, and horizontal symmetry. To detect passing… (More)
– In this paper we present an algorithm for tracking vehicles through an image sequence. The algorithm is based on matching a model in the image plane to each observed vehicle. The model is based on the characteristic edges of an intensity image of a vehicle. This model is applied to track vehicles through image sequences. We introduce three refinements to… (More)
This paper describes a digital rear-view mirror that assists the driver to analyze situations on the road behind him. From the observations of a single camera we want to derive the real-world motion of the vehicles behind our car. These observations are influenced by the egomotion of the camera. In our approach, we use a robust algorithm to estimate the… (More)

In traffic applications research in devices that can increase the safety and comfort of vehicles is an important topic. In this paper a digital rear-view mirror is presented that helps the driver to analyse situations on the road behind him. From the observations from a camera the optical motion in the image plane can be estimated. Based on this motion… (More)
