Segment Anything (SAM) 是什么？
Segment Anything produces object masks from points, boxes or automatic grid prompts. It powers selection tools in many editors and pipelines. Its successor, SAM 2, adds video segmentation.
主要功能
- Point and box prompts for masks
- Automatic mask generation for whole images
- Three model sizes (ViT-B/L/H)
- ONNX export for browser use
系统要求
- 平台
- Windows · macOS · Linux
- 显卡
- NVIDIA recommended
- Python
- 3.8+
如何安装 Segment Anything (SAM)
根据项目 README 整理。开源项目更新很快，请以 GitHub 页面上的最新说明为准。
pip
- 1Install from GitHub.
pip install git+https://github.com/facebookresearch/segment-anything.git - 2Download a checkpoint (e.g. ViT-H) from the README and generate masks.
python scripts/amg.py --checkpoint sam_vit_h_4b8939.pth --model-type vit_h --input image.jpg --output masks/
优势
- Foundation model for segmentation
- Permissive license
不足
- Masks only — no generation
- Large checkpoints
