Aggregation via Separation: Boosting Facial Landmark Detector with Semi-Supervised Style Translation

Shengju Qian, Keqiang Sun, Wayne Wu, Chen Qian, and Jiaya Jia

International Conference on Computer Vision (ICCV), 2019

This repository contains the implementation of our ICCV 2019 paper, 'Aggregation via Separation: Boosting Facial Landmark Detector with Semi-Supervised Style Translation'. The proposed method investigates how to boost the performance of facial landmark detector in limited training resources, using synthetic data in a style-translation manner.

We provide a synthetic WFLW dataset generated by this method here Google Drive or Baidu Drive.

In the provided dataset, each image is augmented with eight different styles in the original WFLW dataset. You may download from this link and are able to produce similar to re-produce the results reported in our paper.

For example, you can train a SAN(CVPR 2018) model using our script.

Avaliable Implementation

Tensorflow

Pytorch(Minimal)

Facial Landmark Detection(SAN)


The instruction of tensorflow implementation is provided in the following:

Prerequisites and Installation

  • Python 3.6
  • Tensorflow 1.2.1
  • CUDA 8.0 and CuDNN 5.1

Getting Started

Clone this repository:

git clone git@github.com:TheSouthFrog/stylealign.git
cd stylealign

Install dependencies using Anaconda:

conda create -n stylealign python=3.6
source activate stylealign
pip install -r requirements.txt

Note this implementation, we use variational u-net as network structure as it produces sharper results.

As it uses a deprecated API of data dependent initialization which requires legacy version of CUDA 8.0 and CuDNN 5.1 without backward compatibility. Prepare Dataset

  • You may the original cropped WFLW dataset here Google Drive or Baidu Drive.
  • Unzip downloaded files. Remember to change the data_dir and image_list to your image directory and annotation file, respectively.

Running the code:

Assume that you have installed multiple versions of CUDA and CuDNN. By switching the environment to run our code, you need to find out the directory where you have installed the right version and run(for example):

export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64

Then run:

CUDA_VISIBLE_DEVICES=gpu_id python main.py --config config/exp_0001.yaml

Generate style-augmented samples

CUDA_VISIBLE_DEVICES=gpu_id python main.py --checkpoint XXXXXX --config config/test_0001.yaml

For acceleration, we use the transfer pass to perform testing, where every image in a batch(batch size: n) outputs n samples under different styles in this batch(n2 in single pass).

gen_landmark.py is used to generate seperated images and corresponding labels of synthetic images according to transfer images and given order in original annotation files.

  • --label_file: The annotation file that used for testing.
  • --checkpoint_iter: Trained Iteration of the testing checkpoint.
  • --batch_size: Testing batch size.
  • --gen_dir and --out_dir: Testing directory and Output directory.
