Estimation of the Acoustic Transducer Beam Aperture by Using the Geometric Backscattering Model for Side-Scan Sonar Systems [PDF]
Sensors, 2023 In this paper, we propose an algorithm for estimating the beam aperture of the acoustic transducers by using the geometric backscattering model for side-scan sonar systems. The geometric backscattering model is developed to describe the propagation paths

A Side-Scan Sonar Image Synthesis Method Based on a Diffusion Model
Journal of Marine Science and Engineering, 2023 The limited number and under-representation of side-scan sonar samples hinders the training of high-performance underwater object detection models. To address this issue, in this paper, we propose a diffusion model-based method to augment side-scan sonar

A Gray Scale Correction Method for Side-Scan Sonar Images Based on Retinex
Remote Sensing, 2019 When side-scan sonars collect data, sonar energy attenuation, the residual of time varying gain, beam patterns, angular responses, and sonar altitude variations occur, which lead to an uneven gray level in side-scan sonar images.

AUV-Based Side-Scan Sonar Real-Time Method for Underwater-Target Detection
Journal of Marine Science and Engineering, 2023 The limitations of underwater acoustic communications mean that the side-scan sonar data of an autonomous underwater vehicle (AUV) cannot be transmitted back and processed in real time, which means that targets cannot be detected in real time. To address

A Curvelet-Transform-Based Image Fusion Method Incorporating Side-Scan Sonar Image Features
Journal of Marine Science and Engineering, 2023 Current methods of fusing side-scan sonar images fail to tackle the issues of shadow removal, preservation of information from adjacent strip images, and maintenance of image clarity and contrast. To address these deficiencies, a novel curvelet-transform-

Side-scan Sonar Image De-noising Based on Bidimensional Empirical Mode Decomposition and Non-local Means [PDF]
E3S Web of Conferences, 2020 In order to suppress the multiplicative specular noise in side-scan sonar images, a denoising method combining bidimensional empirical mode decomposition and non-local means algorithm is proposed.
