PhysDNet: Physics-Guided Decomposition Network of Side-Scan Sonar Imagery

Can Lei, Hayat Rajani, Nuno Gracias +2

Side-scan sonar (SSS) imagery is widely used for seafloor mapping and underwater remote sensing, yet the measured intensity is strongly influenced by seabed reflectivity, terrain e…

Coarse-to-Fine Non-Rigid Registration for Side-Scan Sonar Mosaicking

Can Lei, Nuno Gracias, Rafael Garcia +2

Side-scan sonar mosaicking plays a crucial role in large-scale seabed mapping but is challenged by complex non-linear, spatially varying distortions due to diverse sonar acquisitio…

A Geometrically Consistent Matching Framework for Side-Scan Sonar Mapping

Can Lei, Hayat Rajani, Nuno Gracias +2

Robust matching of side-scan sonar imagery remains a fundamental challenge in seafloor mapping due to view-dependent backscatter, shadows, and geometric distortion. This paper prop…
