Ship Detection in SAR Images with Human-in-the-Loop (2401.08213v1)

Abstract: Synthetic aperture radar (SAR) has been extensively utilized in maritime domains due to its all-weather, all-day monitoring capabilities, particularly exhibiting significant value in ship detection. In recent years, deep learning methods have increasingly been utilized for refined ship detection. However, learning-based methods exhibit poor generalization when confronted with new scenarios and data, necessitating expert intervention for continuous annotation. Currently, the degree of automation in human-machine collaboration within this field, especially in annotating new data, is not high, leading to labor- and computation-intensive model iteration and updates. Addressing these issues, a ship detection framework in SAR images with human-in-the-loop (HitL) is proposed. Incorporating the concept of HitL, tailored active learning strategies are designed for SAR ship detection tasks to present valuable samples to users, and an interactive human-machine interface (HMI) is established to efficiently collect user feedback. Consequently, user input is utilized in each interaction round to enhance model performance. Employing the proposed framework, an annotated ship database of SAR images is constructed, and the iteration experiments conducted during the construction demonstrates the efficiency of the method, providing new perspectives and approaches for research in this domain.
