Official pytorch implementation of [Grounding DINO](https://arxiv.org/abs/2303.05499), a stronger open-set object detector. Code is available now!


## Highlight

- **Open-Set Detection.** Detect **everything** with language!
- **High Performancce.** COCO zero-shot **52.5 AP** (training without COCO data!). COCO fine-tune **63.0 AP**.
- **Flexible.** Collaboration with Stable Diffusion for Image Editting.

## TODO 

- [x] Release inference code and demo.
- [x] Release checkpoints.
- [ ] Grounding DINO with Stable Diffusion and GLIGEN demos.

## Install 

If you have a CUDA environment, please make sure the environment variable `CUDA_HOME` is set.

```bash
pip install -e .
```

## Demo

See the `demo/inference_on_a_image.py` for more details.
```bash
CUDA_VISIBLE_DEVICES=6 python demo/inference_on_a_image.py \
  -c /path/to/config \
  -p /path/to/checkpoint \
  -i .asset/cats.png \
  -o "outputs/0" \
  -t "cat ear."
```

## Acknowledgement

Our model is related to [DINO](https://github.com/IDEA-Research/DINO) and [GLIP](https://github.com/microsoft/GLIP). Thanks for their great work!

We also thank great previous work including DETR, Deformable DETR, SMCA, Conditional DETR, Anchor DETR, Dynamic DETR, DAB-DETR, DN-DETR, etc. More related work are available at [Awesome Detection Transformer](https://github.com/IDEACVR/awesome-detection-transformer). A new toolbox [detrex](https://github.com/IDEA-Research/detrex) is available as well.

Thanks [Stable Diffusion](https://github.com/Stability-AI/StableDiffusion) and [GLIGEN](https://github.com/gligen/GLIGEN) for their awesome models.
