<div align="center">🚀 EDTalk: Efficient Disentanglement for Emotional Talking Head Synthesis</div>

🎏 Abstract

Achieving disentangled control over multiple facial motions and accommodating diverse input modalities greatly enhances the application and entertainment of the talking head generation. This necessitates a deep exploration of the decoupling space for facial features, ensuring that they <strong>a)</strong> operate independently without mutual interference and <strong>b)</strong> can be preserved to share with different modal inputs—both aspects often neglected in existing methods. To address this gap, this paper proposes a novel <strong>E</strong>fficient <strong>D</strong>isentanglement framework for <strong>Talk</strong>ing head generation (<strong>EDTalk</strong>). Our framework enables individual manipulation of mouth shape, head pose, and emotional expression, conditioned on both video and audio inputs. Specifically, we employ three <strong>lightweight</strong> modules to decompose the facial dynamics into three distinct latent spaces representing mouth, pose, and expression, respectively. Each space is characterized by a set of learnable bases whose linear combinations define specific motions. To ensure independence and accelerate training, we enforce orthogonality among bases and devise an <strong>efficient</strong> training strategy to allocate motion responsibilities to each space without relying on external knowledge. The learned bases are then stored in corresponding banks, enabling shared visual priors with audio input. Furthermore, considering the properties of each space, we propose Audio-to-Motion module for audio-driven talking head synthesis. Experiments are conducted to demonstrate the effectiveness of EDTalk.

💻 Overview

🔥 Update

• 2024.09.20 - If you want to compare EDTalk in neutral talking head generation without emotional expression for the coming ICLR and CVPR, demo_lip_pose.py is recommended.
• 2024.08.28 - 🎉 I give a presentation about EDTalk at https://byuih.xetlk.com/sl/40yc8X (But it's in Chinese~).
• 2024.08.12 - 🎉 Our paper is selected as an oral presentation.
• 2024.08.09 - 💻 Add the training code for fine-tuning on a specific person, and we take Obama as example.
• 2024.08.06 - 🙏 We hope more people can get involved, and we will promptly handle pull requests. Currently, there are still some tasks that need assistance, such as creating a colab notebook, improved web UI, and translation work, among others.

EDTalk-A:lip+pose+exp: Run the demo in audio-driven setting (EDTalk-A):

For user-friendliness, we extracted the weights of eight common sentiments in the expression base. one can directly specify the sentiment to generate emotional talking face videos (recommended)

python demo_EDTalk_A_using_predefined_exp_weights.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_type type/of/expression --save_path path/to/save

# example:
python demo_EDTalk_A_using_predefined_exp_weights.py --source_path res/results_by_facesr/demo_EDTalk_A.png --audio_driving_path test_data/mouth_source.wav --pose_driving_path test_data/pose_source1.mp4 --exp_type angry --save_path res/demo_EDTalk_A_using_weights.mp4

Or you can input an expression reference (image/video) to indicate expression.

python demo_EDTalk_A.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_driving_path path/to/expression --save_path path/to/save

# example:
python demo_EDTalk_A.py --source_path res/results_by_facesr/demo_EDTalk_A.png --audio_driving_path test_data/mouth_source.wav --pose_driving_path test_data/pose_source1.mp4 --exp_driving_path test_data/expression_source.mp4 --save_path res/demo_EDTalk_A.mp4

The result will be stored in save_path.

Source_path and videos used must be first cropped using scripts crop_image2.py (download shape_predictor_68_face_landmarks.dat and put it in ./data_preprocess dir) and crop_video.py. Make sure the every video' frame rate must be 25 fps

You can also use crop_image.py to crop the image, but increase_ratio has to be carefully set and tried several times to get the optimal result.

EDTalk-A:lip+pose without exp: If you don't want to change the expression of the identity source, please download the EDTalk_lip_pose.pt and put it into ./ckpts.

If you only want to change the lip motion of the identity source, run

 python demo_lip_pose.py --fix_pose --source_path path/to/image --audio_driving_path path/to/audio --save_path path/to/save
 # example:
 python demo_lip_pose.py --fix_pose --source_path test_data/identity_source.jpg --audio_driving_path test_data/mouth_source.wav --save_path res/demo_lip_pose_fix_pose.mp4

Or you can additionally control the head poses on top of the above via pose_driving_path

 python demo_lip_pose.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --save_path path/to/save

 # example:
 python demo_lip_pose.py --source_path test_data/identity_source.jpg --audio_driving_path test_data/mouth_source.wav --pose_driving_path test_data/pose_source1.mp4 --save_path res/demo_lip_pose_fix_pose.mp4

And control the lip motion via a driven video.

 python demo_lip_pose_V.py --source_path path/to/image --audio_driving_path path/to/audio --lip_driving_path path/to/mouth --pose_driving_path path/to/pose --save_path path/to/save

# example:
 python demo_lip_pose_V.py --source_path res/results_by_facesr/demo_lip_pose5.png --audio_driving_path test_data/mouth_source.wav --lip_driving_path test_data/mouth_source.mp4 --pose_driving_path test_data/pose_source1.mp4 --save_path demo_lip_pose_V.mp4

Change the lip motion of a source video, run:

 python demo_change_a_video_lip.py --source_path path/to/video --audio_driving_path path/to/audio --save_path path/to/save

 # example
 python demo_change_a_video_lip.py --source_path test_data/pose_source1.mp4 --audio_driving_path test_data/mouth_source.wav --save_path res/demo_change_a_video_lip.mp4

Run the demo in video-driven setting (EDTalk-V):

python demo_EDTalk_V.py --source_path path/to/image --lip_driving_path path/to/lip --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_driving_path path/to/expression --save_path path/to/save

# example:
python demo_EDTalk_V.py --source_path test_data/identity_source.jpg --lip_driving_path test_data/mouth_source.mp4 --audio_driving_path test_data/mouth_source.wav --pose_driving_path test_data/pose_source1.mp4 --exp_driving_path test_data/expression_source.mp4 --save_path res/demo_EDTalk_V.mp4

The result will be stored in save_path.

Face Super-resolution (Optional)

☺️🙏 Thanks to Tao Liu for the proposal~

The purpose is to upscale the resolution from 256 to 512 and address the issue of blurry rendering.

Please install addtional environment here:

pip install facexlib
pip install tb-nightly -i https://mirrors.aliyun.com/pypi/simple
pip install gfpgan

Then enable the option --face_sr in your scripts. The first time will download the weights of gfpgan (you can optionally first download gfpgan ckpts and put them in gfpgan/weights dir).

Here are some examples:

python demo_lip_pose.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --save_path path/to/save --face_sr

python demo_EDTalk_V.py --source_path path/to/image --lip_driving_path path/to/lip --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_driving_path path/to/expression --save_path path/to/save --face_sr

python demo_EDTalk_A_using_predefined_exp_weights.py --source_path path/to/image --audio_driving_path path/to/audio --pose_driving_path path/to/pose --exp_type type/of/expression --save_path path/to/save --face_sr

🎬 Fine tune on a specific person

There are a few issues currently, I'll be checking them carefully. Please be patient! Note: We take Obama and the path in my computer (/data/ts/xxxxxx) as example and you should replace it with your own path:

• Download the Obama data from AD-Nerf and put it in '/data/ts/datasets/person_specific_dataset/AD-NeRF/video/Obama.mp4'

• Crop video and resample as 25 fps:

  python data_preprocess/crop_video.py --inp /data/ts/datasets/person_specific_dataset/AD-NeRF/video/Obama.mp4  --outp /data/ts/datasets/person_specific_dataset/AD-NeRF/video_crop/Obama.mp4 
  

• Save video as frames:

  ffmpeg -i /data/ts/datasets/person_specific_dataset/AD-NeRF/video_crop/Obama.mp4 -r 25 -f image2 /data/ts/datasets/person_specific_dataset/AD-NeRF/video_crop_frame/Obama/%4d.png
  

• Start training:

  python train_fine_tune.py --datapath /data/ts/datasets/person_specific_dataset/AD-NeRF/video_crop_frame/Obama --only_fine_tune_dec
  

  Change datapath as your own data. only_fine_tune_dec means only training dec module. In my experience, training only dec can help with image quality, so we recommend it. You also can set it as False, and it means to fune tune full model. You should go through the saved samples (at exp_path/exp_name/checkpoint and in my case, at: /data/ts/checkpoints/EDTalk/fine_tune/Obama/checkpoint) frequently to find the optimal model in time.

First line is source image, second line is driving image, and third line is generated results.

🎬 Data Preprocess for Training

We only use *Front* videos and extract audios and orgnize the data as follows:

```text
/dir_path/MEAD_front/
|-- Original_video
|   |-- M003#angry#level_1#001.mp4
|   |-- M003#angry#level_1#002.mp4
|   |-- ...
|-- audio
|   |-- M003#angry#level_1#001.wav
|   |-- M003#angry#level_1#002.wav
|   |-- ...
```

2) HDTF. download link.

We orgnize the data as follows:

```text
/dir_path/HDTF/
|-- audios
|   |-- RD_Radio1_000.wav
|   |-- RD_Radio2_000.wav
|   |-- ...
|-- original_videos
|   |-- RD_Radio1_000.mp4
|   |-- RD_Radio2_000.mp4
|   |-- ...
```

• Crop videos in training datasets:

  python data_preprocess/data_preprocess_for_train/crop_video_MEAD.py
  python data_preprocess/data_preprocess_for_train/crop_video_HDTF.py
  

• Split video: Since the video in HDTF is too long, we split both the video and the corresponding audio into 5s segments:

  python data_preprocess/data_preprocess_for_train/split_HDTF_video.py
  

  python data_preprocess/data_preprocess_for_train/split_HDTF_audio.py
  

• We save the video frames in a lmdb file to improve I/O efficiency:

  python data_preprocess/data_preprocess_for_train/prepare_lmdb.py
  

• Extract mel feature from audio:

  python data_preprocess/data_preprocess_for_train/get_mel.py
  

• Extract landmarks from cropped videos:

  python data_preprocess/data_preprocess_for_train/extract_lmdk.py
  

• Extract bboxs from cropped videos for lip discriminator using extract_bbox.py and we give an unclean example using lmdb like :

  python data_preprocess/data_preprocess_for_train/extract_bbox.py
  

• After the preprocessing, the data should be orgnized as follows:

  /dir_path/MEAD_front/
  |-- Original_video
  |   |-- M003#angry#level_1#001.mp4
  |   |-- M003#angry#level_1#002.mp4

  |-- video
  |   |-- M003#angry#level_1#001.mp4
  |   |-- M003#angry#level_1#002.mp4
  |   |-- ...
  |-- audio
  |   |-- M003#angry#level_1#001.wav
  |   |-- M003#angry#level_1#002.wav
