    • Active contours for synthetic aperture sonar snippet registration 

      Dugelay, Samantha; Fox, Warren L. J. (CMRE, 2019/06)
      In mine-hunting operations, there is currently a strong focus on using autonomous systems in order to remove personnel and ships from the minefield. These systems must perform their missions effectively, and the collected ...

    • Automatic change detection for the monitoring of cluttered underwater areas 

      Coiras, Enrique; Groen, Johannes; Evans, Benjamin; Pinto, Marc A. (NURC, 2008/09)
      Automating the surveillance of cluttered underwater areas (such as ports) poses several problems, the main one being the high number of contacts that any automatic target recognition (ATR) system will produce when surveying ...

    • Exploiting phase information in synthetic aperture sonar images for target classification 

      Williams, David P. (CMRE, 2019/05)
      It is demonstrated that the phase information present in complex high-frequency synthetic aperture sonar (SAS) imagery can be exploited for successful object classification. That is, without using the amplitude content of ...

    • Forward looking sonar mosaicing for mine countermeasures 

      Ferreira, Fausto; Djapic, Vladimir; Micheli, Michele; Caccia, Massimo (CMRE, 2019/06)
      Forward looking sonars (FLS) are nowadays popular for many different applications. In particular, they can be used for Automatic Target Recognition (ATR) in the context of Mine Countermeasures. Currently, ATR techniques ...

    • The new muesli complexity metric for mine-hunting difficulty in sonar images 

      Williams, David P. (CMRE, 2019/05)
      A new image complexity metric has been developed that fuses the concept of lacunarity, a measure of pixel intensity variation, with the notion of spatial information, a quantity that captures edge energy. This new metric, ...
