Rotate-and-Render: Unsupervised Photorealistic Face Rotation from Single-View Images (CVPR 2020)

Hang Zhou*, Jihao Liu*, Ziwei Liu, Yu Liu, and Xiaogang Wang.

[Paper] [Video]

We propose a novel un-supervised framework that can synthesize photorealistic rotated faces using only single-view image collections in the wild. Our key insight is that rotating faces in the 3D space back and forth, and re-rendering them to the 2D plane can serve as a strong self-supervision.


  • Python 3.6 is used. Basic requirements are listed in the 'requirements.txt'.
pip install -r requirements.txt
  • Install the Neural_Renderer following the instructions.

  • Download checkpoint and BFM model from, put it in 3ddfa and unzip it. Our 3D models are borrowed from 3DDFA.


Rotate faces with examples provided

  1. Download the checkpoint and put it in ./checkpoints/rs_model.

  2. Run a simple Rotate-and-Render demo, the inputs are stored at 3ddfa/example.

  • Modify experiments/, the --poses are the desired degrees (range -90 to 90), choose 0 as frontal face.

  • Run bash experiments/, results will be saved at ./results/.


Prepare your own dataset for testing and training.


  1. Save the 3D params of human faces to 3ddfa/results by 3ddfa.
cd 3ddfa
python --img_list example/file_list.txt --img_prefix example/Images --save_dir results
cd ..

Data Preparation

Modify class dataset_info() inside data/, then prepare dataset according to the pattern of the existing example. You can add the information about a new dataset to each instance of the class.

  1. prefix The absolute path to the dataset.
  2. file_list The list of all images, the absolute path could be incorrect as it is defined in the prefix
  3. land_mark_list The list that stores all landmarks of all images.
  4. params_dir the path that stores all the 3D params processed before.
  5. dataset_names the dictionary that maps dataset NAMEs to their information. This is used in the parsers as --dataset NAME.
  6. folder_level the level of folders from the prefix to images (.jpgs). For example the folder_level is 2 if a image is stored as prefix/label/image.jpg.

Training and Inference

  • Modify experiments/ and use bash experiments/ for training on new datasets.

  • Visualization is supported during training with Tensorboard.

  • Please see the DEMO part for inference.

Details of the Models

We provide two models with trainers in this repo, namely rotate and rotatespade. The "rotatespade" model is an upgraded one which is different from that described in our paper. A conditional batchnorm module is added according to landmarks predicted from the 3D face. Our checkpoint is trained on this model. We have briefly described this model in our supplementary materials.
