A Robust and Fast Method for Sidescan Sonar Image Segmentation Based on Region Growing [PDF]
For high-resolution side scan sonar images, accurate and fast segmentation of sonar images is crucial for underwater target detection and recognition. However, due to the characteristics of low signal-to-noise ratio (SNR) and complex environmental noise ...

Absolute Localization of Targets Using a Phase-Measuring Sidescan Sonar in Very Shallow Waters
The detection, classification, and localization of targets or features on the seafloor in acoustic data are critical to many disciplines. This is most important in cases where human safety is in jeopardy, such as hazards to navigation, mitigation of mine

Towards Differentiable Rendering for Sidescan Sonar Imagery [PDF]
Recent advances in differentiable rendering, which allow calculating the gradients of 2D pixel values with respect to 3D object models, can be applied to estimation of the model parameters by gradient-based optimization with only 2D supervision. It is easy to incorporate deep neural networks into such an optimization pipeline, allowing the leveraging ...

On the Information Advantage of Sidescan Sonar Three-Frequency Colour over Greyscale Imagery
A prototype three-frequency (114, 256, and 410 kHz) colour sidescan sonar system, built by Kongsberg Underwater Mapping Ltd. (Great Yarmouth, UK), was previously described, and preliminary results presented, in Tamsett, McIlvenny, and Watts.
