VoLux-GAN: A Generative Model for 3D Face Synthesis with HDRI Relighting. (arXiv:2201.04873v1 [cs.CV])

We propose VoLux-GAN, a generative framework to synthesize 3D-aware faces
with convincing relighting. Our main contribution is a volumetric HDRI
relighting method that can efficiently accumulate albedo, diffuse and specular
lighting contributions along each 3D ray for any desired HDR environmental map.
Additionally, we show the importance of supervising the image decomposition
process using multiple discriminators. In particular, we propose a data
augmentation technique that leverages recent advances in single image portrait
relighting to enforce consistent geometry, albedo, diffuse and …
