Accurate detection of spread-spectrum modulated signals in reverberant underwater environments
(Elsevier, 2015-02)
In those positioning systems based on the detection of acoustic signals, an accurate detection of the arrival times is crucial for a correct estimation of the distance between nodes, and therefore, for the precise estimation ...

(Elsevier Sci LTDOxford, 2017)
In-air versus underwater comparison of 3D reconstruction accuracy using action sport cameras
(Journal of Biomechanics, 2018)
A node-based method for SLAM navigation in self-similar underwater environments: A case study
(MDPI AG, 2017-10)
This work deals with the development of a node-based monocular visual methodology for autonomous vehicle navigation which has the goal of exploring unknown regions of the sea bottom with a posterior safe revisiting of them. ...
Concrete cracking control in underwater marine structures using basalt fiber
(IOP Publishing Ltd, 2021-02-05)
The construction of coastal ports requires the use of materials that meet the demands of the marine environment, to prevent underwater concrete structures from cracking and spalling easily; basalt fiber is used to delay ...
Proposal for underwater structural analysis using the techniques of ESPI and digital holography
(ELSEVIER SCI LTD, 2009)
The purpose of this article is to study the application of the holographic interferometry techniques in the structural analysis of submarine environment. These techniques are widely used today, with applications in many ...
Underwater IoT Network by Blind MIMO OFDM Transceiver Based on Probabilistic Stone's Blind Source Separation
Telecommunications systems with Multi-Input Multi-Output (MIMO) structure using Orthogonal Frequency Division Modulation (OFDM) have great potential for efficient application to a network of Internet of Things (IoT) at a ...
Semantic Segmentation of Underwater Environments Using DeepLabv3+ and Transfer Learning
(SpringerSG, 2022)
The semantic segmentation approach is essential in automated scene analysis, but its application in underwater environments is still limited. Datasets generally have insufficient labeled data, unbalanced data classes, and ...
Estimação automática de parâmetros de modelos para restauração de imagens de cenas subaquáticas
(Universidade Federal de Minas GeraisUFMG, 2008-07-10)
A large number of techniques to extract information contained in images have been developed through the years. However, these techniques are based on the premise that objects and observer are immersed in a transparent ...
