Extensions | Grounding DINO with Segment Anything; Grounding DINO with Stable Diffusion; Grounding DINO with GLIGEN

Official PyTorch implementation of Grounding DINO, 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.

Description

Paper introduction. Marrying Grounding DINO and GLIGEN

⭐ Explanations/Tips for Grounding DINO Inputs and Outputs

• Grounding DINO accepts an (image, text) pair as inputs.
• It outputs 900 (by default) object boxes. Each box has similarity scores across all input words. (as shown in Figures below.)
• We defaultly choose the boxes whose highest similarities are higher than a box_threshold.
• We extract the words whose similarities are higher than the text_threshold as predicted labels.
• If you want to obtain objects of specific phrases, like the dogs in the sentence two dogs with a stick., you can select the boxes with highest text similarities with dogs as final outputs.
• Note that each word can be split to more than one tokens with differetn tokenlizers. The number of words in a sentence may not equal to the number of text tokens.
• We suggest separating different category names with . for Grounding DINO.

🏷️ TODO

• Release inference code and demo.
• Release checkpoints.
• Grounding DINO with Stable Diffusion and GLIGEN demos.
• Release training codes.

🛠️ Install

If you have a CUDA environment, please make sure the environment variable CUDA_HOME is set. It will be compiled under CPU-only mode if no CUDA available.

pip install -e .

▶️ Demo

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." \
  [--cpu-only] # open it for cpu mode

See the demo/inference_on_a_image.py for more details.

Web UI

We also provide a demo code to integrate Grounding DINO with Gradio Web UI. See the file demo/gradio_app.py for more details.

Notebooks

• We release demos to combine Grounding DINO with GLIGEN for more controllable image editings.
• We release demos to combine Grounding DINO with Stable Diffusion for image editings.

♥️ Acknowledgement

Our model is related to DINO and 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. A new toolbox detrex is available as well.

Thanks Stable Diffusion and GLIGEN for their awesome models.
