StyleGAN2 may be one of the most well known face generator AI systems, but when using it, small details like facial hair and wrinkles did not move organically. These froze in the same spots, but with NVIDIA’s Alias-Freen GAN, all of these small details transform coherently, and the same applies when generating the morphs, or when images slowly shift from one to another.
NVIDIA’s Alias-Free GAN processes images in a vastly different way compared to StyleGAN2, and one example would be the multi-scale phase signals that follow the features. These signals in the final image must control both the appearance and the relative positions of the features.
- NVIDIA GeForce RTX 3050 Ti 4GB GDDR6 up to 1585MHz at 60W (75W with Dynamic Boost 2.0)
- Intel Core i7-11370H processor (12M Cache, up to 4.8GHz)
- 15.6” 144Hz IPS-Type Full HD (1920x1080) display with adaptive sync
Interpreting all signals in the network as continuous, we derive generally applicable, small architectural changes that guarantee that unwanted information cannot leak into the hierarchical synthesis process. The local-oriented oscillations form a basis that enables hierarchical localization. The construction appears to make it natural for the network to construct them from the low-frequency input Fourier features,” said NVIDIA.
