What is SAM?
SAM 2 is the first unified model to segment objects in both images and videos, letting you select the object you want with clicks, boxes, or masks. A per-session memory module tracks objects across all video frames, using information from earlier frames even when an object is briefly occluded. Its streaming architecture processes frames one at a time, enabling real-time interaction. Meta has released the pretrained models, the SA-V dataset, a demo, and code.
- Unified object segmentation for images and videos
- Select objects with click, box, or mask prompts
- Track objects across video frames with a memory module
- Refine mask predictions with additional prompts
- Real-time processing through streaming inference
- Strong zero-shot performance on objects not seen in training
- SA-V dataset released (about 51,000 videos, 600,000+ masklets)
- Training and fine-tuning code and web demo code released
Who uses SAM and for what
- Use as input to other AI systems, such as video generation models, for precise editing
