Is SAM 2 Better than SAM in Medical Image Segmentation?

Understand

The Segment Anything Model (SAM) has demonstrated impressive performance in zero-shot promptable segmentation on natural images.

• The recently released Segment Anything Model 2 (SAM 2) claims to outperform SAM on images and extends the model's capabilities to video segmentation.
• Evaluating the performance of this new model in medical image segmentation, specifically in a zero-shot promptable manner, is crucial.
• In this work, we conducted extensive studies using multiple datasets from various imaging modalities to compare the performance of SAM and SAM 2.
