We present FaceVerse, a fine-grained 3D Neural Face Model, which is built from hybrid East Asian face datasets containing 60K fused RGB-D images and 2K high-fidelity 3D head scan models. A novel coarse-to-fine structure is proposed to take better advantage of our hybrid dataset. In the coarse module, we generate a base parametric model from large-scale RGB-D images, which is able to predict accurate rough 3D face models in different genders, ages, etc. Then in the fine module, a conditional StyleGAN architecture trained with high-fidelity scan models is introduced to enrich elaborate facial geometric and texture details. Note that different from previous methods, our base and detailed modules are both changeable, which enables an innovative application of adjusting both the basic attributes and the facial details of 3D face models. Furthermore, we propose a single-image fitting framework based on differentiable rendering. Rich experiments show that our method outperforms the state-of-the-art methods.

Please download the zip file of version 0 or version 1 (recommended) and unzip it in the ./data folder.
FaceVerse V3, full head model and jittor-based tracking, has been released now.
FaceVerse version 0 Download:[Google Drive] [Baidu Netdisk](6l10): paper version.
Fig.2 Single-image reconstruction results of version 0 (base model, detail model and expression refined final model).
Download:[Google Drive] [Baidu Netdisk](x6wk):
-
Refine the shape of the base PCA model: symmetrical and more detailed.
-
Remove the points inside the mouth.
-
Refine the expression PCA components.
Fig.3 Single-image reconstruction results of version 1 (base model, detail model and expression refined final model).
Download:[Google Drive] [Baidu Netdisk](9n9e) (only the PCA base model for video tracking, please use version 1 for image fitting):
-
Fit the expression components to the 52 blendshapes defined by Apple. Please check 'exp_name_list' in faceverse_simple_v2.npy for the mapping relation.
-
Provide a simplification option (normal with 28632 vertices, simplified with 6335 vertices): you can use the selected points of FaceVerse v2 by:
python tracking_online.py --version 2 --use_simplification
python tracking_offline.py --input example/videos/test.mp4 --res_folder example/video_results --version 2 --use_simplification
- Refine the shape of the base PCA model: orthogonalization.
Fig.4 Real-time online tracking results (30 fps) of version 2. This version is accelerated by point-base rendering using cuda (this version can be used in version 3).
Full head model & jittor-based tracking has been released now, See FaceVersev3 in faceversev3_jittor for more details.

You need to compile the ops provided by stylegan2-pytorch using ninja:
cd third_libs/stylegan_ops
python3 setup.py install
Reconstructing a 3D face from a single image. There are three processes: (a) reconstructed by PCA model; (b) refined by the detailed generator; (c) refined by the expression generator.
An example input with a image folder (sampled from the FFHQ dataset):
python3 fit_images.py --version 1 --input example/images --res_folder example/image_results --save_ply --align
Note: the detailed refinement is based on differentiable rendering, which is quite time-consuming (over 10 minutes). --align is used to crop the input image.
Offline tracking input with a video (our code will crop the face region using the first frame, --use_simplification can be only used for version >= 2):
python tracking_offline.py --input example/videos/test.mp4 --res_folder example/video_results --version 2
Online tracking using your PC camera (our code will crop the face region using the first frame, --use_simplification can be only used for version >= 2):
python tracking_online.py --version 2
Note: the tracking is based on differentiable rendering and only has 2 fps.
