A laparoscopic segmentation foundation model, LapFM, builds comprehensive surgical scene understanding by using a hierarchical concept evolving pre-training paradigm that effectively leverages massive unlabeled data. This approach yields enhanced segmentation accuracy and generalization across various anatomical structures, tissues, and instruments, notably outperforming prior methods on specific surgical categories and unseen datasets.
Key insights
- Massive unlabeled surgical data can be transformed into high-quality supervision through a confidence-driven, iterative pseudo-labeling mechanism, reducing reliance on manual annotations.
- A unified hierarchical taxonomy for surgical concepts, coupled with an adaptive mask decoder, facilitates consistent semantic understanding across varied granularities and entities.
- Dynamic evolution of segmentation capabilities through active exploration of unlabeled data enables strong generalization to unseen surgical categories and adaptive traversal of concept granularities.
