News

(2023-03-14) The training guidance has been released, train DCT-Net with your own style data.

(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).

Web Demo

• Integrated into Colab notebook. Try out the colab demo.

• Integrated into Huggingface Spaces 🤗 using Gradio. Try out the Web Demo

• [Chinese version] Integrated into ModelScope. Try out the Web Demo

Requirements

• python 3
• tensorflow (>=1.14, training only support tf1.x)
• easydict
• numpy
• both CPU/GPU are supported

Quick Start

git clone https://github.com/menyifang/DCT-Net.git
cd DCT-Net

Installation

conda create -n dctnet python=3.7
conda activate dctnet
pip install --upgrade tensorflow-gpu==1.15 # GPU support, use tensorflow for CPU only
pip install "modelscope[cv]==1.3.2" -f https://modelscope.oss-cn-beijing.aliyuncs.com/releases/repo.html
pip install "modelscope[multi-modal]==1.3.2" -f https://modelscope.oss-cn-beijing.aliyuncs.com/releases/repo.html

Downloads

anime	3d	handdrawn	sketch	artstyle

design	illustration

Pre-trained models in different styles can be downloaded by

python download.py

Inference

• from python SDK

python run_sdk.py

• from source code

python run.py

Video cartoonization

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

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:

design	watercolor	illustration	clipart	flat

• Generate stylized data, style choice [option: clipart, design, illustration, watercolor, flat]

python generate_data.py --style clipart

• preprocess

extract aligned faces from raw style images:

python extract_align_faces.py --src_dir 'data/raw_style_data'

• train content calibration network

install environment required by stylegan2-pytorch

cd source/stylegan2
python prepare_data.py '../../data/face_cartoon' --size 256 --out '../../data/stylegan2/traindata'
python train_condition.py --name 'ffhq_style_s256' --path '../../data/stylegan2/traindata' --config config/conf_server_train_condition_shell.json

after training, generated content calibrated samples via:

python style_blend.py --name 'ffhq_style_s256'
python generate_blendmodel.py --name 'ffhq_style_s256' --save_dir '../../data/face_cartoon/syn_style_faces'

• geometry calibration

run geometry calibration for both photo and cartoon:

cd source
python image_flip_agument_parallel.py --data_dir '../data/face_cartoon'
python image_scale_agument_parallel_flat.py --data_dir '../data/face_cartoon'
python image_rotation_agument_parallel_flat.py --data_dir '../data/face_cartoon'

• train texture translator

The dataset structure is recommended as:

+—data
|   +—face_photo
|   +—face_cartoon

resume training from pretrained model in similar style,

style can be chosen from 'anime, 3d, handdrawn, sketch, artstyle, sd-design, sd-illustration'

python train_localtoon.py --data_dir PATH_TO_YOU_DATA --work_dir PATH_SAVE --style anime
