    • 3D terrengmodell generert på bakgrunn av data fra digital bildeanalyse 

      Palm, Hans Christian; Braathen, Bjørn (2003)
      This report describes a technique for generating a digital terrain model of a given scene. The technique is based on first estimating the position and distance to parallelograms placed in various parts of the scene by ...
    • An ATR architecture for algorithm development and testing 

      Breivik, Gøril Margrethe; Løkken, Kristin Hammarstrøm; Brattli, Alvin Andreas; Palm, Hans Christian; Haavardsholm, Trym Vegard (2013)
      A research platform with four cameras in the infrared and visible spectral domains is under development at the Norwegian Defence Research Establishment (FFI). The platform will be mounted on a high-speed jet aircraft and ...
    • Classification based on fast and robust approximations to order statistics 

      Palm, Hans Christian (2020-04-22)
      A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system may be mounted on a jet aircraft or may be used in a land-based ...
    • Detection of military objects in LADAR images 

      Palm, Hans Christian; Ajer, Halvor; Haavardsholm, Trym Vegard (2008)
      This report describes different techniques for preprocessing, segmentation, and detection of vehicle sized objects in LADAR images. Five preprocessing strategies are presented; 1) Median filtering, 2) Two 1-D median ...
    • Extraction and classification of vehicles in LADAR imagery 

      Palm, Hans Christian; Haavardsholm, Trym Vegard; Ajer, Halvor; Jensen, Cathrine V. (2013)
      The work presented in this paper is based on a dataset recorded with an airborne sensor. It comprises targets like M-60, M-47, M-113, bridge layers, tank retrievers, and trucks in various types of scenes. The background-object ...
    • Fast and robust image processing algorithms based on approximations to order statistics 

      Palm, Hans Christian (2018)
      A test system with four cameras in the infrared and visual spectra is under development at FFI (The Norwegian Defence Research Establishment). The system can be mounted on a high speed jet aircraft, but may also be used ...
    • Fusjon av informasjon fra perimeterovervåkingssensorer 

      Palm, Hans Christian (2004)
      This report first describes in detail three standard methods for sensor fusion; rule based fusion, Bayesian fusion, and Dempster Shafer fusion. Next, it is described how information from various surveillance sensors can ...
    • Imaging ground sensor system OPAK 

      Grinaker, Stein; Palm, Hans Christian (2003-09-18)
      Architecture and technology of imaging intrusion detection sensor OPAK are presented. Applications and desired features for IDS and UGS are compared. Started developments of OPAK towards an unattended ground sensor system ...
    • Investigating robustness of adversarial camouflage (AC) for naval vessels 

      Løkken, Kristin; Aurdal, Lars; Brattli, Alvin Andreas; Palm, Hans Christian (2020-09-20)
      The use of camouflage is widespread in the biological domain, and has also been used extensively by armed forces around the world in order to make visual detection and classification of objects of military interest ...
    • Kamerastativer til bruk i et deployerbart perimeterovervåkingssystem 

      Palm, Hans Christian; Jødahl, Hege; Braathen, Bjørn (2004)
      The security of troops participating in international operations are utmost important. A well performing perimeter sur-veillance of the camps is hence required. Cameras will likely be a part of such systems either as a ...
    • Robustness of adversarial camouflage (AC) for naval vessels 

      Løkken, Kristin; Brattli, Alvin Andreas; Palm, Hans Christian; Aurdal, Lars; Klausen, Runhild Aae (2020-04-24)
      Different types of imaging sensors are frequently employed for detection, tracking and classification of naval vessels. A number of countermeasure techniques are currently employed against such sensors, and with the advent ...
