Unlocking Enterprise AI Value
This paper introduces a novel pipeline for reconstructing high-fidelity, relightable, and animatable 3D facial avatars from a limited number of uncalibrated images. By tightly coupling Gaussian Splatting with an explicit triangulated surface, leveraging semantic segmentation, and incorporating PCA-based albedo regularization, our method produces assets compatible with standard graphics pipelines, demonstrating superior geometric accuracy and texture disentanglement compared to prior work.

Applications & Benefits
Our core methodology combines Gaussian Splatting with an explicit mesh, utilizing soft constraints and semantic segmentation to achieve highly accurate geometry and texture reconstruction.
We disentangle albedo from lighting using a relightable Gaussian Splatting model and PCA-based texture regularization, creating de-lit, high-resolution textures suitable for any graphics pipeline.
The pipeline generates animatable facial avatars compatible with MetaHuman, enabling text-driven asset creation and robust performance across disparate capture conditions.

Case Study: Text-Driven Avatar Creation
Leveraging our pipeline with generative AI tools like ChatGPT and Veo 3.
The Challenge: Traditionally, creating high-fidelity, animatable 3D avatars requires extensive manual effort and specialized capture equipment.
Our Solution: We integrate text-to-image (ChatGPT) and text-to-video (Veo 3) generation to simulate our capture setup, feeding the generated content into our pipeline. This automates the initial data acquisition for a base avatar.
The Results: This drastically reduces the initial asset creation time, allowing rapid prototyping of new avatars directly from descriptive text prompts, maintaining high fidelity and animatability.
