Journal of Marine Science and Engineering, 2021 Visual observations of the marine biodiversity can be difficult in specific areas for different reasons, including weather conditions or a lack of observers. In such conditions, passive acoustics represents a potential alternative approach. The objective

Underwater breadcrumb localization
OCEANS 2023 - Limerick, 2023 In most cases, underwater localization implies a fusion of two or more sensors, usually inertial and acoustic ones. Acoustic localization demands the deployment of the acoustic baseline if precise measurement is needed. Using a fixed predeployed baseline limits the accuracy of location estimates outside certain operating areas defined by the baseline ...

3DupIC: An Underwater Scan Matching Method for Three-Dimensional Sonar Registration
Sensors, 2022 This work presents a six degrees of freedom probabilistic scan matching method for registration of 3D underwater sonar scans. Unlike previous works, where local submaps are built to overcome measurement sparsity, our solution develops scan matching ...

Underwater Single Image Color Restoration Using Haze-Lines and a New Quantitative Dataset [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2018 Underwater images suffer from color distortion and low contrast, because light is attenuated while it propagates through water. Attenuation under water varies with wavelength, unlike terrestrial images where attenuation is assumed to be spectrally ...

Advanced Engineering Materials, EarlyView.This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.
