About this paper
Yichi Zhang, Zhenrong Shen
This survey paper by Zhang and Shen evaluates the application of Segment Anything Model 2 (SAM2) to biomedical images and videos, highlighting its potential for reducing annotation burden and enabling zero-shot segmentation, while emphasizing that successful implementation often requires domain-specific adaptation to overcome the inherent differences between natural and medical data.
Key insights
- SAM2's direct application to 3D medical images yields variable results, underscoring a significant 'domain gap' between its natural image training and medical data characteristics.
- SAM2 demonstrates more robust performance on medical videos, such as surgical footage, largely because their visible-light nature results in a smaller domain gap compared to medical scans.
- Effective deployment and improved accuracy of SAM2 in biomedical contexts critically depend on implementing domain-specific adaptation and fine-tuning techniques to bridge the natural-to-medical data divide.
