Research on Small Target Detection in Sonar Images Using Improved DEIM Based on Diffusion-GAN Data Augmentation

Small-target detection in side-scan sonar images is challenging due to weak target responses, low contrast, complex target–shadow structures, and strong seabed texture interference, especially under limited annotated data. To address these challenges, this paper proposes a data–model co-optimization framework that comb...
