Instance Segmentation and Localization of Overlapping Subsurface Rocks in GPR Images Using ConvNeXt and Hybrid Task Cascade

Small subsurface rocks pose significant challenges to drilling operations during lunar regolith sampling missions. Ground-penetrating radar (GPR), a nondestructive detection technique, provides high-resolution subsurface imaging; however, accurately interpreting rock echoes remains challenging due to signal interference. This study proposes a novel instance segmentation framework to accurately ide...
