[Summary] Relightable Gaussian Codec Avatars
TL;DR Photorealistic head avatars is a required technology for virtual and augmented reality. However, current approaches either lack the fidelity to capture fine details (like hair) or are too slow for real-time use. Relightable Gaussian Codec Avatars proposes using (i) 3D Gaussian splatting for efficient geometry representation and (ii) a learnable radiance transfer model for appearance, including an explicit eye model. Background Image relighting is the task of showing what a scene from a source image would look like if illuminated differently....
