FFHQ-UV is a large-scale facial UV-texture dataset that contains over 50,000 high-quality texture UV-maps with even illuminations, neutral expressions, and cleaned facial regions, which are desired characteristics for rendering realistic 3D face models under different lighting conditions.

The dataset is derived from a large-scale face image dataset namely FFHQ, with the help of our fully automatic and robust UV-texture production pipeline. Our pipeline utilizes the recent advances in StyleGAN-based facial image editing approaches to generate multi-view normalized face images from single-image inputs. An elaborated UV-texture extraction, correction, and completion procedure is then applied to produce high-quality UV-maps from the normalized face images. Compared with existing UV-texture datasets, our dataset has more diverse and higher-quality texture maps.

• Please refer to this [README] for details of checkpoints and topology assets.

Create FFHQ-UV dataset

• Please refer to this [README] for details of running facial UV-texture dataset creation pipeline.
• Microsoft Face API is not accessible for new users, one can find an alternative API, or manually fill in the json file to avoid this step.
• We provide the detected facial attributes of the FFHQ dataset we used, please find details from here.

RGB fitting

• Please refer to this [README] for details of running RGB fitting process.
• We provide a new version of RGB fitting, where the FFHQ-UV-Interpolate dataset is used and the GAN-based texture decoder only generates facial textures. More details can found here.

Add eyeballs into head mesh

• Prepare a head mesh with HiFi3D++ topology, which is without eyeballs.
• Modify the configuration and then run the following script to add eyeballs into head mesh.

sh run_mesh_add_eyeball.sh  # Please refer to this script for detailed configuration

Generate a UV-texture map from a single facial image

There are two ways to generate a UV-texture map from a given facial image:

1. Facial editing + texture unwrapping (Section 3.1 of the paper)
2. RGB fitting (Section 4.2 of the paper)

1. UV-texture map from: facial editing + texture unwrapping

• The FFHQ-UV dataset is created from the FFHQ dataset in this way.
• See source codes of facial UV-texture dataset creation pipeline, which including GAN inversion, attribute detection, StyleGAN-based editing, and texture unwrapping steps.
• Advantages:
  • The generated textures are directly extracted from facial images, which are detailed and with high-quality.
• Disadvantages:
  • The GAN inversion step would be failed for some samples.
  • The attribute detection step requires the Microsoft Face API, which is no longer accessible.
  • The StyleGAN-based editing would change the ID of the faces, resulting in textures with low-fidelity.

2. UV-texture map from: RGB fitting

• This is the proposed 3D face reconstruction algorithm, which uses FFHQ-UV dataset to train a nonlinear texture basis.
• See source codes of RGB fitting.
• Advantages:
  • The generated textures are fitted based on the supervision of input faces, which are with high-fidelity.
• Disadvantages:
  • The textures are generated by a GAN-based texture decoder, sometimes with less detail than texture maps in the FFHQ-UV dataset. This is mainly due to the limitations of the nonlinear texture basis design and training.
  • Future work will improve the generation capabilities of the nonlinear texture basis, in order to take full advantage of the high-quality and detailed UV texture maps in the FFHQ-UV dataset.

Using our UV-texture maps on a FLAME mesh

• We provide a solution for using our UV-texture maps on a FLAME mesh, please refer to this [README] for details.
