In this report we present the rst results of a very eecient scheme for vehicle detection in traac scenes. It is based on the detection of the shadows underneath the vehicles. The use of shadow as sign pattern was rst reported in 5]. Herein a histogram evaluation of the paved road sustains the speciication of a threshold value for the shaded areas. This(More)
— Sophisticated fuzzy rule systems are supposed to be flexible, complete, consistent and compact (FC 3). Flexibility, completeness and consistency are essential for fuzzy systems to exhibit an excellent performance and to have a clear physical meaning, while compactness is crucial when the number of the input variables increases. However, the completeness(More)
Systems for automated image analysis are useful for a variety of tasks and their importance is still increasing due to technological advances and an increase of social acceptance. Especially in the field of driver assistance systems the progress in science has reached a level of high performance. Fully or partly autonomously guided vehicles, particularly(More)
Robot systems, which are employed outside traditional manufacturing applications, so-called service robots or robot assistants, have by far not reached the economic potential of industrial robots yet. There are several factors, which explain this circumstance. Operating robots in unmodified natural environments inhabited by human beings imposes requirements(More)
— Behavior planning of a vehicle in real-world traffic is a difficult problem. Complex systems have to be build to accomplish the projection of tasks, environmental constraints, and purposes of the driver to the dynamics of two controlled variables: steering angle and velocity. This paper comprises two parts. First, the behavior planning for the task of(More)
(d) (e) Fig. 11 Pedestrian tracking (a) (b) (c) (d) (e) Fig. 12 Vehicle tracking achieves superior speed and accuracy through the introduction of several performance enhancing techniques. The method-specific optimizations also enhance overall system performance without affecting worst-case execution times. These optimizations apply to various region-based(More)
Maintaining efficient transportation systems has become a key goal for government-based transportation agencies in this age of serious energy shortages, rising costs and competing recipients of public funds. The emphasis has shifted to optimizing traffic movement on the existing surface street network rather than to provide more freeways. As described in(More)
We report on the work done at the Institut f ur Neuroinfor-matik in Bochum concerning the development of a neural architecture for the information processing of autonomous visually guided systems acting in a natural environment. Since biological systems like our brain are superior to artiicial systems in solving such a task, we use ndings from(More)
Behavioural research, neurophysiological experiments and computer simulations are used in an attempt to analyze pattern recognition in the cat's visual system. The methods were chosen in such a way that the measurable performance data resulting from behavioural and neurophysiological experiments can be combined simply. It is shown that, with minor(More)
