[Project] [Paper]

Given an audio clip and a target video, our Emotional Video Portraits (EVP) approach is capable of generating emotion-controllable talking portraits and change the emotion of them smoothly by interpolating at the latent space.

Installation

We train and test based on Python3.6 and Pytorch. To install the dependencies run:

pip install -r requirements.txt

Testing

• Download the pre-trained models and data under the following link: google-drive (we release results of two target person: M003 and M030), unzip the test.zip and put the file in corresponding places.

• Step1 : audio2landmark

  The emotion of predicted landmark motions can be manipulated by the emotion features (recommanded):

  python audio2lm/test.py --config config/target_test.yaml --audio path/to/audio --condition feature --emo_feature path/to/feature
  

  or by the emotional audio of the target person:

  python audio2lm/test.py --config config/target_test.yaml --audio path/to/audio --condition feature --emo_audio path/to/emo_audio
  

  The results will be stored in results/target.mov

• Step2 : landmark2video

  A parametric 3D face model and the corresponding fitting algorithm should be used here to regress the geometry, expression and pose parameters of the predicted landmarks and the target video. Here we release some parameters of the testing results.

  lm2video/data/target/3DMM/3DMM: images and landmark positions of the video

  lm2video/data/target/3DMM/target_test: parameters of target's video

  lm2video/data/target/3DMM/target_test_pose: pose parameters of video

  lm2video/data/target/3DMM/test_results: parameters of predicted landmarks

  Here we use vid2vid to generate video from edgemaps:

  1. Generate the testing data by running:

     python lm2video/lm2map.py
     

     and copy the results in lm2video/results/ to vid2vid/datasets/face/.

  2. Replace the face_dataset.py and base_options.py in vid2vid to lm2video/face_dataset.py and lm2video/base_options.py, the 106 keypoint version.

  3. Copy lm2video/data/target/latest_net_G0.pth to vid2vid/checkpoints/target/ , lm2video/test_target.sh to vid2vid/scripts/face and run:

     bash ./scripts/face/test_target.sh
     

Training

• Download the pre-trained models and data under the following link: google-drive (we release data of M030), unzip the train.zip and put the file in corresponding places.

• Step1 : emotion_pretrain:

1. Generate the trainig data(MFCC) from the raw audio:

   python emotion_pretrain/code/mfcc_preprocess.py
   

2. The emotion classification for MFCC:

    python emotion_pretrain/code/train.py
   

• Step2 : disentanglement

1. Use DTW to align the audio:

   python disentanglement/dtw/MFCC_dtw.py
   

2. Cross-reconstruction for disentanglement:

    python disentanglement/code/train_content+cla.py
   

• Step3 : landmark

1. Generate the data for training:

   python landmark/code/preprocess.py
   

2. Training the Audio-to-Landmark module:

    python landmark/code/train.py
