Comparison of synthetic aperture sonar images and optical images of UXOs from the Skagerrak chemical munitions dumpsite
(2019-11-28)
After World War II chemical munitions were loaded onto large ships and sunk
in the Skagerrak Strait in the Norwegian trench, in deep waters between Norway and Denmark. In collaboration with the Norwegian Coastal Administration, ...
A wavelet schrinkage approach to detect candidate point scatterers in synthetic aperture sonar images for resolution estimation
(2023)
Autonomous Underwater Vehicles (AUVs) that are equipped with side-looking synthetic aperture
sonar (SAS) have become a popular asset for efficient high resolution imaging and mapping of the
seafloor. There are situations ...
3D Rendering of Shipwrecks from Synthetic Aperture Sonar
(2021-10-25)
Synthetic aperture sonar (SAS) bathymetric mapping provides centimeter-scale horizontal resolution of the
seafloor. Typically, SAS data has been visualized as 2D images or gridded 2.5D surfaces, but it can also be
plotted ...
A Study on the Effect of Commonly Used Data Augmentation Techniques on Sonar Image Artifact Detection Using Deep Neural Networks
(2023-10-20)
This paper presents an empirical study that evaluates the impact of different types of augmentations on the performance of Deep Learning (DL) models for detecting imaging artifacts in Synthetic Aperture Sonar (SAS) imagery. ...
Uncertainty quantification with deep learning through variational inference with applications to synthetic aperture sonar
(2023)
Deep learning (DL) has gained popularity in applications and research within the active sonar community both in academic and commercial settings due to the ability of such models to learn complex non-linear relationships ...
