  • Tymkovych, Maksym Yu; Avrunin, Oleg G.; Paliy, Victor G.; Filzow, Maksim; Gryshkov, Oleksandr; Glasmacher, Birgit; Omiotek, Zbigniew; Dzierlak, Roza; Smailova, Saule; Kozbekova, Ainur (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    The work is dedicated to the segmentation problem of human nasal airways using Cone Beam Computed Tomography. During research, we propose a specialized approach of structured segmentation of nasal airways. That approach ...
  • Pollak, Bernd; Jacobsen, Karsten (London : International Society for Photogrammetry and Remote Sensing, 2000)
    The geometric changes of the surface (subsidence and horizontal displacement) caused by coal mining can be determined by photogrammetry with a sufficient accuracy. As long time stable targets sewer manholes can be used. ...
  • Gaa, Johannes; Kahrs, Lüder Alexander; Müller, Samuel; Majdani, Omid; Ortmaier, Tobias (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Planning and analyzing of surgical interventions are often based on computer models derived from computed tomography images of the patient. In the field of cochlear implant insertion the modeling of several structures of ...
  • Altmann, Bettina; Pape, Christian; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Unstable movement in roller bearings like cage or roller slip can lead to damages or eventually even to an early break of the bearing. To prevent slip, inadequate operating states should be avoided. Therefore, it is necessary ...
  • Fuchs, Alexander; Pengel, Steffen; Bergmeier, Jan; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Laser surgery is an established clinical procedure in dental applications, soft tissue ablation, and ophthalmology. The presented experimental set-up for closed-loop control of laser bone ablation addresses a feedback ...
  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Inspection of machine elements is an important task in production processes in order to ensure the quality of produced parts and to gather feedback for the continuous improvement process. A new measuring system is presented, ...
  • Menze, Moritz; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2014)
    Three-dimensional information from dense image matching is a valuable input for a broad range of vision applications. While reliable approaches exist for dedicated stereo setups they do not easily generalize to more ...
  • Kruse, C.; Rottensteiner, F.; Heipke, C. (London : International Society for Photogrammetry and Remote Sensing, 2019)
    Many countries were the target of air strikes during the Second World War. The aftermath of such attacks is felt until today, as numerous unexploded bombs or duds still exist in the ground. Typically, such areas are ...
  • Rath, Thomas; Pastrana, Julio (Darmstadt : Kuratorium für Technik und Bauwesen in der Landwirtschaft e. V. (KTBL), 2012)
    In order to solve the overlapping problem that occurs when performing identification of single plants, a computer base pattern recognition system was implemented. The presented technique has 3 general steps: The recognition ...
  • Bergmeier, Jan; Kundrat, Dennis; Schoob, Andreas; Kahrs, Lüder Alexander; Ortmaier, Tobias (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    This work investigates combination of Optical Coherence Tomography and two cameras, observing a microscopic scene. Stereo vision provides realistic images, but is limited in terms of penetration depth. Optical Coherence ...
  • 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 ...
  • Gerke, M.; Nex, F.; Remondino, F.; Jacobsen, Karsten; Kremer, J.; Karel, W.; Huf, H.; Ostrowski, W. (Göttingen : Copernicus GmbH, 2016)
    During the last decade the use of airborne multi camera systems increased significantly. The development in digital camera technology allows mounting several mid- or small-format cameras efficiently onto one platform and ...
  • Bergmeier, Jan; Fast, Jacob Friedemann; Ortmaier, Tobias; Kahrs, Lüder Alexander (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Image-to-physical registration based on volumetric data like computed tomography on the one side and intraoperative endoscopic images on the other side is an important method for various surgical applications. In this ...
  • Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Hannover : International Society for Photogrammetry and Remote Sensing, 2013)
    The General Directorate of Surveying and Mapping (GDSM), under the Ministry of Municipal and Rural Affairs (MOMRA) is responsible for the production and dissemination of accurate geospatial data for all the metropolitan ...
