      There is a significant need for reliable, cost-effective, and preferably automatic methods for detecting and monitoring marine gas seeps. Seeps at the seafloor may originate from natural sources including sediments releasing ...

    • Automatic detection of oil spills by SAR images : dark spot detection and feature extraction 

      Brekke, Camilla (2005)
      This report is written in the context of a PhD-study. The research is aiming at exploiting the potential of automatic detection of oil spills using new, advanced algorithms to demonstrate how well such a system will perform ...

    • Automatic object recognition within point clouds in clustered or scattered scenes 

      Bae, Egil (2020)
      We consider the problem of automatically locating, classifying and identifying an object within a point cloud that has been acquired by scanning a scene with a ladar. The recent work [E. Bae, Automatic scene understanding ...
