## News
(2023-02-20) Two new style pre-trained models (design, illustration) trained with combined DCT-Net and Stable-Diffusion are provided. The training guidance will be released soon.

(2022-10-09) The multi-style pre-trained models (3d, handdrawn, sketch, artstyle) and usage are available now. 

(2022-08-08) The pertained model and infer code of 'anime' style is available now. More styles coming soon.

(2022-08-08) cartoon function can be directly call from pythonSDK.

(2022-07-07) The paper is available now at arxiv(https://arxiv.org/abs/2207.02426).

Pre-trained models in different styles can be downloaded by
```bash
python download.py
```

### Inference

- from python SDK
```bash
python run_sdk.py
```

- from source code
```bash
python run.py
```

### Video cartoonization

![demo_vid](assets/video.gif)

video can be directly processed as image sequences, style choice [option: anime, 3d, handdrawn, sketch, artstyle, sd-design, sd-illustration]

```bash
python run_vid.py --style anime
```


## Training

### Data preparation
```
face_photo: face dataset such as [FFHQ](https://github.com/NVlabs/ffhq-dataset) or other collected real faces.
face_cartoon: 100-300 cartoon face images in a specific style, which can be self-collected or synthsized with generative models.
```
Due to the copyrighe issues, we can not provide collected cartoon exemplar for training. You can produce cartoon exemplars with the style-finetuned Stable-Diffusion (SD) models, which can be downloaded from modelscope or huggingface hubs.

The effects of some style-finetune SD models are as follows:

- Generate stylized data, style choice [option: clipart, design, illustration, watercolor, flat]
```bash
python generate_data.py --style clipart
```
