Query: Self-supervised High-fidelity and Re-renderable 3D Facial Reconstruction
  from a Single Image   Reconstructing high-fidelity 3D facial texture from a single image is a
challenging task since the lack of complete face information and the domain gap
between the 3D face and 2D image. The most recent works tackle facial texture
reconstruction problem by applying either generation-based or
reconstruction-based methods. Although each method has its own advantage, none
of them is capable of recovering a high-fidelity and re-renderable facial
texture, where the term 're-renderable' demands the facial texture to be
spatially complete and disentangled with environmental illumination. In this
paper, we propose a novel self-supervised learning framework for reconstructing
high-quality 3D faces from single-view images in-the-wild. Our main idea is to
first utilize the prior generation module to produce a prior albedo, then
leverage the detail refinement module to obtain detailed albedo. To further
make facial textures disentangled with illumination, we present a novel
detailed illumination representation which is reconstructed with the detailed
albedo together. We also design several regularization loss functions on both
the albedo side and illumination side to facilitate the disentanglement of
these two factors. Finally, thanks to the differentiable rendering technique,
our neural network can be efficiently trained in a self-supervised manner.
Extensive experiments on challenging datasets demonstrate that our framework
substantially outperforms state-of-the-art approaches in both qualitative and
quantitative comparisons.
