This repo holds the pytorch improved re-implementation of paper Face Alignment in Full Pose Range: A 3D Total Solution. Several additional works are added in this repo, including real-time training, training strategy and so on. Therefore, this repo is far more than re-implementation. One related blog will be published for some important technique details in future. As far, this repo releases the pre-trained first-stage pytorch models of MobileNet-V1 structure, the training dataset and code. And the inference time is about 0.27ms per image (input batch with 128 images) on GeForce GTX TITAN X.

These repo will keep being updated, thus any meaningful issues and PR are welcomed.

Several results on ALFW-2000 dataset (inferenced from model phase1_wpdc_vdc.pth.tar) are shown below.

1. Face Alignment


2. Face Reconstruction


3. 3D Pose Estimation


Getting started


  • PyTorch >= 0.4.1
  • Python >= 3.6 (Numpy, Scipy, Matplotlib)
  • Dlib (Dlib is used for detecting face and landmarks. There is no need to use Dlib if you can provide face bouding bbox and landmarks. Optionally, you can use the two-step inference strategy without initialized landmarks.)
  • OpenCV (Python version, for image IO opertations.)
  • Platform: Linux or macOS (Windows is not tested)
# installation structions
sudo pip3 install torch torchvision # for cpu version. more option to see
sudo pip3 install numpy scipy matplotlib
sudo pip3 install dlib==19.5.0 # 19.15+ version may cause conflict with pytorch, this may take several minutes
sudo pip3 install opencv-python

In addition, I strongly recommend using Python3.6+ instead of older version for its better design.


  1. Clone this repo (this may take some time as it is a little big)

    git clone  # or
    cd 3DDFA

    Then, download dlib landmark model in Google Drive or Baidu Yun, and put it into models directory. (To reduce this repo's size, I remove some large size binary files including this model, so you should download it : ) )

  2. Run the with arbitrary image as input

    python3 -f samples/test1.jpg

    If you can see these output log in terminal, you run it successfully.

    Dump tp samples/test1_0.ply
    Save 68 3d landmarks to samples/test1_0.txt
    Dump tp samples/test1_1.ply
    Save 68 3d landmarks to samples/test1_1.txt
    Dump to samples/test1_pose.jpg
    Save visualization result to samples/test1_3DDFA.jpg

    Because test1.jpg has two faces, there are two mat (stores dense face vertices, can be rendered by Matlab, see visualize) and ply files (can be rendered by Meshlab or Microsoft 3D Builder) predicted.

    Please run python3 -h or review the code for more details.

    The 68 landmarks visualization result samples/test1_3DDFA.jpg and pose estimation result samples/test1_pose.jpg are shown below



  1. Additional example

    python3 ./ -f samples/emma_input.jpg --bbox_init=two --dlib_bbox=false

Inference speed

When batch size is 128, the inference time of MobileNet-V1 takes about 34.7ms. The average speed is about 0.27ms/pic.

Inference speed


First, you should download the cropped testset ALFW and ALFW-2000-3D in, then unzip it and put it in the root directory. Next, run the benchmark code by providing trained model path. I have already provided five pre-trained models in models directory (seen in below table). These models are trained using different loss in the first stage. The model size is about 13M due to the high efficiency of MobileNet-V1 structure.

python3 ./ -c models/phase1_wpdc_vdc_v2.pth.tar

The performances of pre-trained models are shown below. In the first stage, the effectiveness of different loss is in order: WPDC > VDC > PDC. While the strategy using VDC to finetune WPDC achieves the best result.

The training scripts lie in training directory. The related resources are in below table.

Data Download Link Description
train.configs BaiduYun or Google Drive, 217M The directory contraining 3DMM params and filelists of training dataset BaiduYun or Google Drive, 2.15G The cropped images of augmentation training dataset BaiduYun or Google Drive, 151M The cropped images of AFLW and ALFW-2000-3D testset

After preparing the training dataset and configuration files, go into training directory and run the bash scripts to train. The training parameters are all presented in bash scripts.


  1. Face bounding box initialization

    The original paper validates that using detected bounding box instead of ground truth box will cause a little performance drop. Thus the current face cropping method is robustest. Quantitative results are shown in below table.
