Method overview

High-Level structure

The code is organized as follows:

• Code/main.py is the main program for generating photographs.
• Code/Stage2/ckpt we provide link to download model weights. See details in Code/Stage2/ckpt/download_ckpt.txt.
• Code/Stage3/ckpt we provide link to download model weights. See details in Code/Stage3/ckpt/download_ckpt.txt.
• Data/ is the directory for saving input images, we provide one testing case here.
• Output/ is the directory for saving output images.

How to Use

Get started

We run with Python 3.7 on Windows, you can set up a conda environment with all dependencies according to Code/requirements.txt.

Download model weights

• Refer to the links in Code/Stage2/ckpt/download_ckpt.txt, download the model weights and put as Code/Stage2/ckpt/ckpt_contour2contour_mixed_v2_ContourSegm_4000.pth.
• Refer to the links in Code/Stage3/ckpt/download_ckpt.txt, download the model weights and put as Code/Stage3/ckpt/ckpt_contour2tooth_v2_ContourSegm_facecolor_lightcolor_10000.pth.

Prepare data

Prepare some facial photographs for testing and then put them under path Data/. Here Data/case1.jpg is an example.

Usage

Simply use the following command to run our code. You will see the results in Output/prediction and Output/processing.

   cd Code
   python main.py -i ../Data/case1.jpg
