## :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 

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

## :hammer_and_wrench: Install 

**Note:**

0. 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: 
```bash
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:
```bash
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. 
```bash
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:

```bash
echo 'export CUDA_HOME=/path/to/cuda' >> ~/.bashrc
```
after that, source the bashrc file and check CUDA_HOME:
```bash
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:
```bash
export CUDA_HOME=/usr/local/cuda
```
**Installation:**

1.Clone the GroundingDINO repository from GitHub.

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

2. Change the current directory to the GroundingDINO folder.

```bash
cd GroundingDINO/
```

3. Install the required dependencies in the current directory.

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

4. Download pre-trained model weights.

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

## :arrow_forward: Demo
Check your GPU ID (only if you're using a GPU)

```bash
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
```bash
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:
```bash
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:**

```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](demo/image_editing_with_groundingdino_gligen.ipynb) to combine [Grounding DINO](https://arxiv.org/abs/2303.05499) with [GLIGEN](https://github.com/gligen/GLIGEN)  for more controllable image editings.
- We release [demos](demo/image_editing_with_groundingdino_stablediffusion.ipynb) to combine [Grounding DINO](https://arxiv.org/abs/2303.05499) with [Stable Diffusion](https://github.com/Stability-AI/StableDiffusion) 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**.

```bash
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
```
