  • 3D feature point extraction from LiDAR data using a neural network 
    Feng, Yu; Schlichting, Alexander; Brenner, Claus (Göttingen : Copernicus GmbH, 2016)
    Accurate positioning of vehicles plays an important role in autonomous driving. In our previous research on landmark-based positioning, poles were extracted both from reference data and online sensor data, which were then ...
  • Junction extraction by artificial neural network system – Jeans 
    Barsi, Arpad; Heipke, Christian; Willrich, Felicitas ([Wechselnde Verlagsorte] : ISPRS, 2002)
    The paper presents a road junction operator, which was developed for medium resolution black-and-white orthoimages. The operator uses a feed-forward neural network applied for a running window to decide whether it contains ...
  • A new straight line reconstruction methodology from multi-spectral stereo aerial images 
    Ok, A.O.; Wegner, J.D.; Heipke, Christian; Rottensteiner, Franz; Sörgel, Uwe; Toprak, V. (London : International Society for Photogrammetry and Remote Sensing, 2010)
    In this study, a new methodology for the reconstruction of line features from multispectral stereo aerial images is presented. We take full advantage of the existing multispectral information in aerial images all over the ...
