摘要：
SurgiSAM 2 is a fine-tuned foundational model designed for surgical video anatomy segmentation, achieving significant performance improvements over its predecessor, SAM 2. The model demonstrated a 17.9% relative gain in segmentation accuracy and outperformed state-of-the-art methods in 80% of tested classes. By leveraging public surgical datasets, SurgiSAM 2 effectively addresses the challenges of limited annotated data in surgical contexts, paving the way for automated annotation pipelines and enhancing surgical applications such as real-time navigation and skill assessment.
