A method for classification of ground conditions in the vicinity of a vehicle using a radar sensor, comprising: receiving reflected portions of a radar signal at a receiver unit of a radar system; calculating information derived from the received portions of the radar signal for discrete spatial ...
This paper describes a mission synthesis algorithm developed for producing short test signal sequences which are representative of road data records. The algorithm is based on the use of Fourier analysis, orthogonal Daubechies 12 wavelets, and peak correction procedures. Crest factor control with consi...
It is important to correctly determine road condition as it contains essential information for improving traffic safety. Knowledge about the road condition is used by maintenance personnel as a trigger for snow removal and deicing tasks. The presence of severe road conditions is also communicated as...
In this article, we classify road surface statuses using a Bayesian classification method. This article uses principal component analysis (PCA) that combines a 94 GHz dual-channel polarimetric radiometer. The radiometer is used to investigate the behaviour of the brightness temperature (BT) of differe...

Road images are captured by our acquisition system. Firstly, a pre-processing step is applied on images to remove lane-marking. Then an anisotropy measure is calculated to detect road defects. Finally, a backpropagation neural network is used to classify the images into four classes: defect-...
In contrast, pedestrians or bicyclists do not always stay on the road and they often get close to static structure of the environment, e.g. traffic lights or signs, bushes, parking cars etc. These objects are not as easy to segment, often resulting in an under-segmentation of the scene ...
