Treat Noise as Domain Shift: Noise Feature Disentanglement for Underwater Perception and Maritime Surveys in Side-Scan Sonar Images

IEEE Transactions on Geoscience and Remote Sensing, 2023
In underwater perception and maritime surveys, due to the scarcity of training data and perturbation of speckle noise, the detection performance of underwater objects in side-scan sonar (SSS) images is limited.

Object detection in side scan sonar

SPIE Proceedings, 2015
Automatic target detection is a challenging task as the response from an underwater target may vary greatly depending on its configuration, sonar parameters and the environment. We propose a Z- test algorithm for target detection in side scan sonar image which avoids this problem that covers the variation in the target response.

Machine learning for shipwreck segmentation from side scan sonar imagery: Dataset and benchmark

Int. J. Robotics Res.
Open-source benchmark datasets have been a critical component for advancing machine learning for robot perception in terrestrial applications. Benchmark datasets enable the widespread development of state-of-the-art machine learning methods, which ...

Side-Scan Sonar Image Simulation Considering Imaging Mechanism and Marine Environment for Zero-Shot Shipwreck Detection

IEEE Transactions on Geoscience and Remote Sensing, 2023
In the process of side-scan sonar (SSS) image target detection and recognition, the direct application of deep learning techniques will cause serious overfitting due to the limited amount of sonar image sample data, thus restricting the accuracy of ...

Nearshore Side-Scan Sonar Studies

Journal of Atmospheric and Oceanic Technology, 1993
Abstract Side-scan sonars operating at 80–250 kHz have been deployed to produce narrow beams directed parallel and normal to shore on a gently sloping beach. These provide measurements of processes (such as wave propagation) seaward of the edge of the surf zone.

Side scan sonar technology

OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002
Selection of the correct side scan sonar system for a specific application is difficult for the typical ocean operator. The source of this difficulty results from the diversity of side scan sonar designs and a general lack of knowledge on the capabilities and restrictions of available side scan sonar systems.

Segmentation and Classification of Side-Scan Sonar Data

2012
Side scan sonar is an acoustic sensor which uses sound waves to generate side scan sonar images. Most adaptive behavior of AUVs would require that the vehicle be able sense the environment, detect objects of interest, localize and then change its current behavior.

Side-scan sonar image matching

IEEE Journal of Oceanic Engineering, 1998
This paper presents a method for the matching of underwater images acquired with acoustic sensors. As a final objective, the system aims at matching data from two-dimensional scenes. The proposed approach carries out a hypothetical reasoning based on objects, represented by shadows and echoes in the sonar images, and their available features.
