SC-Match: Scale-Space Matching with Context Consistency for Side-Scan Sonar Mapping
Can Lei, Rafael Garcia, Nuno Gracias +2
Reliable estimation of spatial correspondences between overlapping side-scan sonar (SSS) measurements is essential for mapping, but acoustic appearance variations, weak seabed text…
Geometric Correction of Side-Scan Sonar Images with Image-Consistent Attitude Refinement
Can Lei, Valerio Franchi, Hayat Rajani +3
Side-scan sonar (SSS) images are susceptible to motion-induced geometric distortion, which degrades their reliability for seabed interpretation and downstream tasks. Existing corre…
Physically Motivated Knowledge Distillation for Blind Geometric Correction of Side-Scan Sonar Imagery
Can Lei, Hayat Rajani, Valerio Franchi +4
Side-scan sonar (SSS) imagery is susceptible to geometric distortions caused by platform motion instability, which degrade geometric consistency and limit downstream analyses such…
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…
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…
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…
