Netflix Eyeline Studios has introduced DifFRelight, an AI-based diffusion-based framework capable of relighting complex facial performances.DifFRelight allows for precise control over lighting, including complex effects like eye reflections and self-shadowing.The framework takes flat-lit facial captures as input and translates them into images and dynamic sequences with realistic lighting.DifFRelight utilizes a pre-trained diffusion-based image-to-image translation model and the 3D Gaussian Splatting technique.
