S3-Face: SSS-Compliant Facial Reflectance Estimation via Diffusion Priors

Figure 1 . We introduce S 3 -Face, a comprehensive high-quality facial reflectance estimation method. Our approach leverages a pretrained diffusion model as a reflectance prior, robustly generating subsurface scattering (SSS)-compliant facial reflectance, particularly for hemoglobin and melanin maps. S 3 -Face adeptly handles diverse input subjects and formats, delivering photorealistic rendering results.
