RAM is a strong image tagging model, which can recognize any common category with high accuracy.
- **Strong and general.** RAM exhibits exceptional image tagging capabilities with powerful zero-shot generalization;
    - RAM showcases impressive zero-shot performance, significantly outperforming CLIP and BLIP.
    - RAM even surpasses the fully supervised manners (ML-Decoder).
    - RAM exhibits competitive performance with the Google tagging API.
- **Reproducible and affordable.** RAM requires Low reproduction cost with open-source and annotation-free dataset;
- **Flexible and versatile.** RAM offers remarkable flexibility, catering to various application scenarios.

</p>

RAM significantly improves the tagging ability based on the Tag2text framework.
- **Accuracy.** RAM utilizes a **data engine** to **generate** additional annotations and **clean** incorrect ones,  **higher accuracy** compared to Tag2Text.
- **Scope.** RAM upgrades the number of fixed tags from  3,400+ to **[6,400+](./ram/data/ram_tag_list.txt)** (synonymous reduction to 4,500+ different semantic tags), covering **more valuable categories**.
  Moreover, RAM is equipped with **open-set capability**, feasible to recognize tags not seen during training

</details>

Tag2Text is an efficient and controllable vision-language model with tagging guidance.
- **Tagging.** Tag2Text recognizes **[3,400+](./ram/data/tag2text_ori_tag_list.txt)** commonly human-used categories without manual annotations.
- **Captioning.** Tag2Text integrates **tags information** into text generation as the **guiding elements**, resulting in **more controllable and comprehensive descriptions**. 
- **Retrieval.** Tag2Text provides **tags** as **additional visible alignment indicators** for image-text retrieval.

### **Image Texts and Tags**

These annotation files come from the [Tag2Text](https://arxiv.org/abs/2303.05657) and [RAM](https://recognize-anything.github.io/). Tag2Text automatically extracts image tags from image-text pairs. RAM further augments both tags and texts via an automatic data engine.

CC12M to be released in the next update.

### **LLM Tag Descriptions**

These tag descriptions files come from the [RAM++](https://arxiv.org/abs/2310.15200) by calling GPT api. You can also customize any tag categories by [generate_tag_des_llm.py](generate_tag_des_llm.py).

## :running: Model Inference

### **Setting Up** ###

1. Create and activate a Conda environment:

```bash
conda create -n recognize-anything python=3.8 -y
conda activate recognize-anything
```

2. Install `recognize-anything` as a package:

```bash
pip install git+https://github.com/xinyu1205/recognize-anything.git
```

3. Or, for development, you may build from source:

```bash
git clone https://github.com/xinyu1205/recognize-anything.git
cd recognize-anything
pip install -e .
```

Then the RAM++, RAM, and Tag2Text models can be imported in other projects:

```python
from ram.models import ram_plus, ram, tag2text
```

### **RAM++ Inference** ###

Get the English and Chinese outputs of the images:

```bash
python inference_ram_plus.py --image images/demo/demo1.jpg --pretrained pretrained/ram_plus_swin_large_14m.pth
```

The output will look like the following:

```
Image Tags:  armchair | blanket | lamp | carpet | couch | dog | gray | green | hassock | home | lay | living room | picture frame | pillow | plant | room | wall lamp | sit | wood floor
图像标签:  扶手椅  | 毯子/覆盖层 | 灯  | 地毯  | 沙发 | 狗 | 灰色 | 绿色  | 坐垫/搁脚凳/草丛 | 家/住宅 | 躺  | 客厅  | 相框  | 枕头  | 植物  | 房间  | 壁灯  | 坐/放置/坐落 | 木地板
```

### **RAM++ Inference on Unseen Categories (Open-Set)** ##

1. Get the [OpenImages-Uncommon categories](./datasets/openimages_rare_200/openimages_rare_200_ram_taglist.txt) of the image:

We have released the LLM tag descriptions of OpenImages-Uncommon categories in [openimages_rare_200_llm_tag_descriptions](./datasets/openimages_rare_200/).

<pre/>
python inference_ram_plus_openset.py  --image images/openset_example.jpg \
--pretrained pretrained/ram_plus_swin_large_14m.pth \
--llm_tag_des datasets/openimages_rare_200/openimages_rare_200_llm_tag_descriptions.json
</pre>

2. You can also customize any tag categories for recognition through tag descriptions:

Modify [categories](./generate_tag_des_llm.py#L56), and call GPT api to generate corresponding tag descriptions:

<pre/>
python generate_tag_des_llm.py \
--openai_api_key 'your openai api key' \
--output_file_path datasets/openimages_rare_200/openimages_rare_200_llm_tag_descriptions.json
</pre>

<details>
<summary><font size="4" style="font-weight:bold;">

Get the English and Chinese outputs of the images:

<pre/>
python inference_ram.py  --image images/demo/demo1.jpg \
--pretrained pretrained/ram_swin_large_14m.pth
</pre>

The output will look like the following:

```
Image Tags:  armchair | blanket | lamp | carpet | couch | dog | floor | furniture | gray | green | living room | picture frame | pillow | plant | room | sit | stool | wood floor
图像标签:  扶手椅  | 毯子/覆盖层 | 灯  | 地毯  | 沙发 | 狗 | 地板/地面 | 家具  | 灰色 | 绿色  | 客厅  | 相框  | 枕头  | 植物  | 房间  | 坐/放置/坐落 | 凳子  | 木地板 
```

</font></summary>

Firstly, custom recognition categories in [build_openset_label_embedding](./ram/utils/openset_utils.py), then get the tags of the images:

<pre/>
python inference_ram_openset.py  --image images/openset_example.jpg \
--pretrained pretrained/ram_swin_large_14m.pth
</pre>

The output will look like the following:
```
Image Tags: Black-and-white | Go-kart
```

</details>

<details>
<summary><font size="4" style="font-weight:bold;">
Tag2Text Inference
</font></summary>

Get the tagging and captioning results:
<pre/>
python inference_tag2text.py  --image images/demo/demo1.jpg \
--pretrained pretrained/tag2text_swin_14m.pth
</pre>
Or get the tagging and sepcifed captioning results (optional):
<pre/>python inference_tag2text.py  --image images/demo/demo1.jpg \
--pretrained pretrained/tag2text_swin_14m.pth \
--specified-tags "cloud,sky"</pre>

</details>

### **Batch Inference and Evaluation** ##
We release two datasets `OpenImages-common` (214 common tag classes) and `OpenImages-rare` (200 uncommon tag classes). Copy or sym-link test images of [OpenImages v6](https://storage.googleapis.com/openimages/web/download_v6.html) to `datasets/openimages_common_214/imgs/` and `datasets/openimages_rare_200/imgs`.

To evaluate RAM++ on `OpenImages-common`:

```bash
python batch_inference.py \
  --model-type ram_plus \
  --checkpoint pretrained/ram_plus_swin_large_14m.pth \
  --dataset openimages_common_214 \
  --output-dir outputs/ram_plus
```

To evaluate RAM++ open-set capability on `OpenImages-rare`:

```bash
python batch_inference.py \
  --model-type ram_plus \
  -- pretrained/ram_plus_swin_large_14m.pth \
  --open-set \
  --dataset openimages_rare_200 \
  --output-dir outputs/ram_plus_openset
```

To evaluate RAM on `OpenImages-common`:

```bash
python batch_inference.py \
  --model-type ram \
  -- pretrained/ram_swin_large_14m.pth \
  --dataset openimages_common_214 \
  --output-dir outputs/ram
```

To evaluate RAM open-set capability on `OpenImages-rare`:

```bash
python batch_inference.py \
  --model-type ram \
  -- pretrained/ram_swin_large_14m.pth \
  --open-set \
  --dataset openimages_rare_200 \
  --output-dir outputs/ram_openset
```

To evaluate Tag2Text on `OpenImages-common`:

```bash
python batch_inference.py \
  --model-type tag2text \
  -- pretrained/tag2text_swin_14m.pth \
  --dataset openimages_common_214 \
  --output-dir outputs/tag2text
```

Please refer to `batch_inference.py` for more options. To get P/R in table 3 of RAM paper, pass `--threshold=0.86` for RAM and `--threshold=0.68` for Tag2Text.

To batch inference custom images, you can set up you own datasets following the given two datasets.
