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.

Side-Scan Sonar Small Objects Detection Based on Improved YOLOv11

Journal of Marine Science and Engineering
Underwater object detection using side-scan sonar (SSS) remains a significant challenge in marine exploration, especially for small objects. Conventional methods for small object detection face various obstacles, such as difficulties in feature ...

SS-YOLO: A Lightweight Deep Learning Model Focused on Side-Scan Sonar Target Detection

Journal of Marine Science and Engineering
As seabed exploration activities increase, side-scan sonar (SSS) is being used more widely. However, distortion and noise during the acoustic pulse’s travel through water can blur target details and cause feature loss in images, making target recognition

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: Selective Textural Enhancement

OCEANS '76, 1976
A variety of signal processing techniques are available which can assist the interpretation of side-scan sonar. In exploring the range of possibilities for processing with these techniques we have developed selective tuning of textural enhancement for different textural wavelengths. In practice we have found it desirable to be free to decide on tuning,

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.

A new generation side scan sonar

OCEANS '88. 'A Partnership of Marine Interests'. Proceedings, 2003
Side-scan sonar traditionally has used a graphic paper recording system for the display and annotation of the data. A novel side-scan system specifically designed to use color video as the primary data display is described. Several design considerations and tradeoffs are discussed, some of which are unique to a system using a video display.
