## :star: Explanation/Tips for Grounding DINO Inputs and Outputs
- Grounding DINO accepts with a `(image, text)` pair as inputs.
- It will outputs `900` (by default) object boxes. Each box has a similarity scores across all input words.
- We defaultly choose the boxes whose highest similarities are higher than a `box_threshold`.
- We clip the words whose similarities are higher than the `text_threshold` as predicted labels.
- If you want to obtain objects of certain 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.
