Meta's Segment Anything Model (SAM) enables one-click segmentation of any object, dramatically accelerating image annotation for segmentation tasks.
How SAM Works for Annotation
Click on any object and SAM instantly generates a precise segmentation mask. Add positive or negative points to refine the selection for complex objects.
Best Use Cases for SAM
- Instance Segmentation - Objects with clear boundaries
- Medical Imaging - Organs, tumors, anatomical structures
- Product Photography - E-commerce catalog annotation
- Satellite Imagery - Buildings, roads, land use
- Industrial Inspection - Defects and anomalies
SAM Limitations to Consider
SAM may struggle with transparent objects, thin structures, and heavily occluded scenes. Always have annotators review and refine AI-generated masks.
