:star: 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.

:label: TODO

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

:hammer_and_wrench: 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.

Installation:

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.

pip3 install -q -e .

Create a new directory called "weights" to store the model weights.

mkdir weights

Change the current directory to the "weights" folder.

cd weights

Download the model weights file.

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

:arrow_forward: 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/groundingdino/config/GroundingDINO_SwinT_OGC.py \
-p /GroundingDINO/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

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.
