Semantic Segmentation of Side-Scan Sonar Images with Few Samples

Electronics, 2022
Underwater sensing and detection still rely heavily on acoustic equipment, known as sonar. As an imaging sonar, side-scan sonar can present a specific underwater situation in images, so the application scenario is comprehensive.

Side-Scan Sonar Image Classification Based on Style Transfer and Pre-Trained Convolutional Neural Networks

Electronics, 2021
Side-scan sonar is widely used in underwater rescue and the detection of undersea targets, such as shipwrecks, aircraft crashes, etc. Automatic object classification plays an important role in the rescue process to reduce the workload of staff and ...

Multiresolution 3-D Reconstruction From Side-Scan Sonar Images

IEEE Transactions on Image Processing, 2007
In this paper, a new method for the estimation of seabed elevation maps from side-scan sonar images is presented. The side-scan image formation process is represented by a Lambertian diffuse model, which is then inverted by a multiresolution optimization

Side scan sonar and interferometric noise

Oceans '99. MTS/IEEE. Riding the Crest into the 21st Century. Conference and Exhibition. Conference Proceedings (IEEE Cat. No.99CH37008), 2002
This paper concerns the description of different noise sources encountered as well as the impact of each of these sources through sonar interferometric data acquisition. The impact of noise is directly linked to the ability of the Vernier device to determine the 2/spl pi/ ambiguity of the phase measure and to know the altitude of the bottom.

Bistatic side scan sonar

The Journal of the Acoustical Society of America, 1992
This discloses an improved side-scan sonar capable of locating objects on e ocean floor including the strip directly beneath the sonar transmitter and receiver, which in prior arrangements had to be obtained by another pass. The arrangement includes a platform having acoustic transmitters spaced apart a substantial distance on either side of acoustic ...
