A Texture Feature Removal Network for Sonar Image Classification and Detection
Deep neural network (DNN) was applied in sonar image target recognition tasks, but it is very difficult to obtain enough sonar images that contain a target; as a result, the direct use of a small amount of data to train a DNN will cause overfitting and ...

Towards Terrain-Based Navigation Using Side-Scan Sonar
This paper introduces a statistical model and corresponding sequential Bayesian estimation method for terrain-based navigation using side-scan sonar (SSS) data. The presented approach relies on slant range measurements extracted from the received ping of a SSS. In particular, incorporating slant range measurements to landmarks for navigation constrains

A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

Improved AUV navigation using side-scan sonar
The following paper presents results from a novel solution for improving the navigation of an Autonomous Underwater Vehicle (AUV) using a side-scan sonar. It is derived from a system that has been developed to produce high quality mosaics using a Doppler

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets
ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...
