# Pretrained Grounding DINO with Commercial License
## Description
Open vocabulary object detection is a computer vision technique that can detect one or multiple objects in a frame based on the text input. Object detection recognizes the individual objects in an image and places bounding boxes around the object. This model card contains pre-trained weights for the [Grounding DINO](https://arxiv.org/abs/2303.05499) object detection networks pretrained on the commercial dataset. Note that the model in this model card can be used for commercial purpose.

The licenses to use this model is covered by the Model EULA. By downloading the unpruned or pruned version of the model, you accept the terms and conditions of these [licenses](https://www.nvidia.com/en-us/data-center/products/nvidia-ai-enterprise/eula/)
## Model Architecture
**Architecture Type:** Transformer-based Network Architecture
**Network Architecture**
- Backbone: Window attention based Transformers called Swin-Tiny and BERT-Base text encoder.
- Encoder: 6 layers of Multi-headed attention with deformable attention layers.
- Decoders: 6 layers of Multi-headed attention with deformable attention layers.
**More Details**
- The models in this instance are object detectors that take RGB images and list of phrases as input and produce bounding boxes and classes as output. More specifically, this model was trained with [Swin-Tiny backbone](https://arxiv.org/pdf/2103.14030) that was trained using a supervised manner on NVIDIA proprietary data called NVImageNetv2, which allows commercial usage. In addition, BERT-Base was used as the starting weight for text tower. Finally, Grounding DINO was trained end-to-end on about 1.8M images that were collected from publicly available datasets. Note that we ensured that all the raw images used during training have commercial licenses to ensure safe commercial usage.
### Input
**Input Type(s):** Image and list of captions of tokenized through HuggingFace
**Input Format(s):** Red, Green, Blue (RGB) and tokenized inputs. Can support any input resolution and images do not need any additional pre-processing (e.g. alpha channels or bits)
**Input Parameters:** Multiple dimensions. See below for detailed input shapes
**Other Properties Related to Input:**
- `inputs`: B X 3 X 544 X 960 (Batch Size x Channel x Height x Width)
- `input_ids`: B x 256 (Batch Size x Max Token Length )
- `attention_mask`: B x 256 (Batch Size x Max Token Length )
- `position_ids`: B x 256 (Batch Size x Max Token Length )
- `token_type_ids`: B x 256 (Batch Size x Max Token Length )
- `text_token_mask`: B x 256 x 256 (Batch Size x Max Token Length x Max Token Length)
- Because ONNX / TensorRT can't take string as input, we've offloaded tokenizer outside of the model graph. See [TAO-Deploy](https://github.com/NVIDIA/tao_deploy) repo on running tokenization through HuggingFace.
### Output
**Output Type(s):** Bounding Boxes and Confidence Scores for each detected object in the input image.
**Output Formats:** One Dimensional (1D), Two Dimensional (2D) vectors
**Other Properties Related to Output:**
- `pred_logits`: B x 900 (Batch Size x Number of Queries)
- `pred_boxes`: B x 900 x 4 (Batch Size x Number of Queries x Coordinates in `cxcywh` format)

## Model Versions
- **grounding_dino_swin_tiny_commercial_trainable_v1.0** - Pre-trained Swin-Tiny Grounding DINO model for finetune.
- **grounding_dino_swin_tiny_commercial_deployable_v1.0** - Swin-Tiny Grounding DINO model deployable.
## Training & Evaluation:
This model was trained using the `grounding_dino` entrypoint in TAO. The training algorithm optimizes the network to minimize the localization and contrastive embedding loss between text and visual features.
## Using this Model
These models need to be used with NVIDIA hardware and software. For hardware, the models can run on any NVIDIA GPU including NVIDIA Jetson devices. These models can only be used with [Train Adapt Optimize (TAO) Toolkit](https://developer.nvidia.com/tao-toolkit), or [TensorRT](https://developer.nvidia.com/tensorrt).
The intended use for these models is detecting objects in a color (RGB) image. The model can be used to detect objects from photos and videos by using appropriate video or image decoding and pre-processing.
These models are intended for training and fine-tune with the TAO Toolkit and your datasets for object detection. High-fidelity models can be trained with new use cases. A Jupyter Notebook is available as a part of the pytorch [TAO container](https://catalog.ngc.nvidia.com/orgs/nvidia/teams/tao/containers/tao-toolkit/tags) and can be used to re-train.
The models are also intended for easy edge deployment using TensorRT.
## Training Dataset

### Methodology and KPI
The key performance indicator is the mean average precision (mAP), following the standard evaluation protocol for object detection. The KPI for the evaluation data are:
|model|precision|mAP|mAP50|mAP75|mAPs|mAPm|mAPl|
|---|---|---|---|---|---|---|---|
|grounding_dino_swin_tiny|BF16|46.1|59.9|51.0|30.5|49.3|60.8|
## Model Limitation
Grounding DINO was trained on images collected from the web and text data of everyday noun phrases. The model might not perform well on different data distributions. Conducting further fine-tuning on the target domain is recommended to get a higher mAP.
