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)

— In recent years many methods providing the ability to recognize rigid obstacles-sedans and trucks-have been developed. These methods provide the driver with relevant information. They are able to cope reliably with scenarios on motorways. Nevertheless, not much attention has been given to image processing approaches to increase the safety of pedestrians(More)
Introduction. The problems encountered in building a driver assistance system are numerous. The collection of information about real environment by sensors is erroneous and incomplete. When the sensors are mounted on a moving observer it is difficult to find out whether a detected motion was caused by ego-motion or by an independent object moving. The(More)
