Segment Anything Model (SAM)

Comprehensive guide to using Meta AI's Segment Anything Model for zero-shot image segmentation.

When to use SAM

Use SAM when:

• Need to segment any object in images without task-specific training
• Building interactive annotation tools with point/box prompts
• Generating training data for other vision models
• Need zero-shot transfer to new image domains
• Building object detection/segmentation pipelines
• Processing medical, satellite, or domain-specific images

Key features:

• Zero-shot segmentation: Works on any image domain without fine-tuning
• Flexible prompts: Points, bounding boxes, or previous masks
• Automatic segmentation: Generate all object masks automatically
• High quality: Trained on 1.1 billion masks from 11 million images
