Leveraging the extensive training data from SA-1B, Segment Anything Model (SAM) demonstrates remarkable generalization and zero-shot capabilities. However, as a category-agnostic instance segmentation method, SAM heavily relies on prior manual guidance, including points, boxes, coarse-grained masks. Furthermore, its performance in remote sensing image tasks remains largely unexplored unproven. In this paper, we aim to develop an automated approach for images, based foundational model incorporating semantic category information. Drawing inspiration prompt learning, propose method learn generation of appropriate prompts SAM. This enables produce semantically discernible results concept have termed RSPrompter.
