A Bayesian Network Approach to Evaluating the Effectiveness of Modern Mine Hunting

Hammond, Tim R.; Midtgaard, Øivind; Connors, Warren A. (2021-10-29)

This paper describes a novel technique for estimating how many mines remain after a full or partial underwater mine hunting operation. The technique applies Bayesian fusion of all evidence from the heterogeneous sensor ...
Challenges of Automated Change Detection in Repeat-pass Synthetic Aperture Sonar Imagery

Midtgaard, Øivind; Sæbø, Torstein Olsmo; Warakagoda, Narada Dilp (2023)

Change detection extracts regions of interest as temporal differences by imaging a scene before and after changes may have occurred. We denote the initial image as the reference and the more recent as the current image. ...
Multi-phase performance evaluation for modern minehunting systems

Midtgaard, Øivind; Warakagoda, Narada Dilp; Davies, Gary; Connors, Warren A.; Geilhufe, Marc (2019-05-10)

Many NATO navies are in the process of replacing their dedicated minehunting vessels with systems of heterogeneous, unmanned modules. While traditional ship-based assets prosecute sonar contacts in sequence through to ...
