[paper] [video] [project page]

This paper supersedes the previous version of M3-LRN.

Advantages

👍 SOTA on all 3D facial alignment, face orientation estimation, and 3D face modeling.

👍 Fast inference with 3000fps on a laptop RTX 2080.

👍 Simple implementation with only widely used operations.

(This project is built/tested on Python 3.8 and PyTorch 1.9)

Single Image Inference Demo

1. Clone

   git clone https://github.com/choyingw/SynergyNet

   cd SynergyNet

2. Use conda

   conda create --name SynergyNet

   conda activate SynergyNet

3. Install pre-requisite common packages

   PyTorch 1.9 (should also be compatiable with 1.0+ versions), Opencv, Scipy, Matplotlib

4. Download data [here] and [here]. Extract these data under the repo root.

These data are processed from [3DDFA] and [FSA-Net].

Download pretrained weights [here]. Put the model under 'pretrained/'

5. Compile Sim3DR and FaceBoxes:

   cd Sim3DR

   ./build_sim3dr.sh

   cd ../FaceBoxes

   ./build_cpu_nms.sh

   cd ..

6. Inference

   python singleImage.py -f img

Benchmark Evaluation

1. Follow Single Image Inference Demo: Step 1-4

2. Benchmarking

   python benchmark.py -w pretrained/best.pth.tar

Print-out results and visualization under 'results/' (see 'demo/' for some sample references) are shown.

Training

1. Follow Single Image Inference Demo: Step 1-4.

2. Download training data from [3DDFA]: train_aug_120x120.zip and extract the zip file under the root folder (Containing about 680K images).

3. bash train_script.sh

4. Please refer to train_script for hyperparameters, such as learning rate, epochs, or GPU device. The default settings take ~19G on a 3090 GPU and about 6 hours for training. If your GPU is less than this size, please decrease the batch size and learning rate proportionally.

Textured Artistic Face Meshes

1. Follow Single Image Inference Demo: Step 1-5.

2. Download artistic faces data [here], which are from [AF-Dataset]. Download our inferred UV maps [here] by UV-texture GAN. Extract them under the root folder.

3. python artistic.py -f art-all/122.png

Note that this artistic face dataset contains many different level/style face abstration. If a testing image is close to real, the result is much better than those of highly abstract samples.

More Results

We show a comparison with [DECA] using the top-3 largest roll angle samples in AFLW2000-3D.
