Continual Alignment for SAM: Rethinking Foundation Models for Medical Image Segmentation in Continual Learning

arXiv — cs.CVMonday, November 24, 2025 at 5:00:00 AM
  • A new study introduces Continual Alignment for SAM (CA-SAM), a strategy aimed at enhancing the Segment Anything Model (SAM) for medical image segmentation. This approach addresses the challenges of heterogeneous privacy policies across institutions that hinder joint training on pooled datasets, allowing for continual learning from data streams without catastrophic forgetting.
  • The development of CA-SAM is significant as it aims to improve the computational efficiency and performance of SAM, which is crucial for practical deployment in medical imaging. By introducing the Alignment Layer, a lightweight module that aligns feature distributions, the model can adapt more effectively to specific medical images, enhancing accuracy while reducing computational demands.
  • This advancement reflects a broader trend in artificial intelligence where models are increasingly designed for continual learning and adaptability. The integration of lightweight modules like the Alignment Layer signifies a shift towards more efficient AI solutions, paralleling developments in other models such as SAM2S for surgical video segmentation and Medverse for 3D medical imaging, which also focus on overcoming domain-specific challenges.
