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 different 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.

🛠️ Install

Note:

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.

Please make sure following the installation steps strictly, otherwise the program may produce:

NameError: name '_C' is not defined

If this happened, please reinstalled the groundingDINO by reclone the git and do all the installation steps again.

how to check cuda:

echo $CUDA_HOME

If it print nothing, then it means you haven't set up the path/

Run this so the environment variable will be set under current shell.

export CUDA_HOME=/path/to/cuda-11.3

Notice the version of cuda should be aligned with your CUDA runtime, for there might exists multiple cuda at the same time.

If you want to set the CUDA_HOME permanently, store it using:

echo 'export CUDA_HOME=/path/to/cuda' >> ~/.bashrc

after that, source the bashrc file and check CUDA_HOME:

source ~/.bashrc
echo $CUDA_HOME

In this example, /path/to/cuda-11.3 should be replaced with the path where your CUDA toolkit is installed. You can find this by typing which nvcc in your terminal:

For instance, if the output is /usr/local/cuda/bin/nvcc, then:

export CUDA_HOME=/usr/local/cuda

Installation:

1.Clone the GroundingDINO repository from GitHub.

git clone https://github.com/IDEA-Research/GroundingDINO.git

Change the current directory to the GroundingDINO folder.

cd GroundingDINO/

Install the required dependencies in the current directory.

pip install -e .

Download pre-trained model weights.

mkdir weights
cd weights
wget -q https://github.com/IDEA-Research/GroundingDINO/releases/download/v0.1.0-alpha/groundingdino_swint_ogc.pth
cd ..

▶️ Demo

Check your GPU ID (only if you're using a GPU)

nvidia-smi

Replace {GPU ID}, image_you_want_to_detect.jpg, and "dir you want to save the output" with appropriate values in the following command

CUDA_VISIBLE_DEVICES={GPU ID} python demo/inference_on_a_image.py \
-c groundingdino/config/GroundingDINO_SwinT_OGC.py \
-p weights/groundingdino_swint_ogc.pth \
-i image_you_want_to_detect.jpg \
-o "dir you want to save the output" \
-t "chair"
 [--cpu-only] # open it for cpu mode

If you would like to specify the phrases to detect, here is a demo:

CUDA_VISIBLE_DEVICES={GPU ID} python demo/inference_on_a_image.py \
-c groundingdino/config/GroundingDINO_SwinT_OGC.py \
-p ./groundingdino_swint_ogc.pth \
-i .asset/cat_dog.jpeg \
-o logs/1111 \
-t "There is a cat and a dog in the image ." \
--token_spans "[[[9, 10], [11, 14]], [[19, 20], [21, 24]]]"
 [--cpu-only] # open it for cpu mode

The token_spans specify the start and end positions of a phrases. For example, the first phrase is [[9, 10], [11, 14]]. "There is a cat and a dog in the image ."[9:10] = 'a', "There is a cat and a dog in the image ."[11:14] = 'cat'. Hence it refers to the phrase a cat . Similarly, the [[19, 20], [21, 24]] refers to the phrase a dog.

See the demo/inference_on_a_image.py for more details.

Running with Python:

from groundingdino.util.inference import load_model, load_image, predict, annotate
import cv2

model = load_model("groundingdino/config/GroundingDINO_SwinT_OGC.py", "weights/groundingdino_swint_ogc.pth")
IMAGE_PATH = "weights/dog-3.jpeg"
TEXT_PROMPT = "chair . person . dog ."
BOX_TRESHOLD = 0.35
TEXT_TRESHOLD = 0.25

image_source, image = load_image(IMAGE_PATH)

boxes, logits, phrases = predict(
    model=model,
    image=image,
    caption=TEXT_PROMPT,
    box_threshold=BOX_TRESHOLD,
    text_threshold=TEXT_TRESHOLD
)

annotated_frame = annotate(image_source=image_source, boxes=boxes, logits=logits, phrases=phrases)
cv2.imwrite("annotated_image.jpg", annotated_frame)

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.

COCO Zero-shot Evaluations

We provide an example to evaluate Grounding DINO zero-shot performance on COCO. The results should be 48.5.

CUDA_VISIBLE_DEVICES=0 \
python demo/test_ap_on_coco.py \
 -c groundingdino/config/GroundingDINO_SwinT_OGC.py \
 -p weights/groundingdino_swint_ogc.pth \
 --anno_path /path/to/annoataions/ie/instances_val2017.json \
 --image_dir /path/to/imagedir/ie/val2017
