No Distillation Needed: Single-Pass Real-Time Talking Heads via Acausal Noise Shaping
Read the original on arXiv Computer Vision →The paper introduces FaceGAN, a single-pass GAN that generates real-time talking head animations from audio without the need for distillation or diffusion models. By shaping the noise pathway acausally, FaceGAN maintains a causal audio-to-expression mapping while suppressing unwanted spectral artifacts, enabling continuous, drift-free generation at interactive rates. The approach achieves comparable or superior quality to state‑of‑the‑art methods while requiring only one forward pass per frame.
