Gaussian Pixel Codec Avatars: A Hybrid Representation for Efficient Rendering

arXiv — cs.CVThursday, December 18, 2025 at 5:00:00 AM
  • Gaussian Pixel Codec Avatars (GPiCA) have been introduced as a new method for creating photorealistic head avatars from multi-view images, utilizing a hybrid representation of triangle meshes and anisotropic 3D Gaussians for efficient rendering on mobile devices. This innovative approach maximizes memory efficiency while preserving visual fidelity, particularly in rendering facial features and hair.
  • The development of GPiCA is significant as it enhances the capabilities of mobile devices in rendering complex 3D avatars, which can have applications in gaming, virtual reality, and social media, potentially transforming user interactions and experiences in digital environments.
  • This advancement reflects a broader trend in artificial intelligence and computer graphics towards more efficient and realistic rendering techniques, paralleling developments in 3D Gaussian Splatting and other methods aimed at improving the quality and speed of image generation, which are critical for real-time applications in various industries.
