MimicTalk - Create Personalized 3D Talking Faces with AI in Minutes
Based on groundbreaking Real3D-Portrait technology, quickly train and generate high-quality personalized talking avatars
What is MimicTalk ?
MimicTalk is a PyTorch-based open-source project that can train personalized and expressive talking heads in minutes. Built upon our previous work Real3D-Portrait (ICLR 2024), a single-image NeRF-based talking head system that enables fast training and high-quality generation.
MimicTalk Features
Enhanced Transformer Network
At its core, MimicTalk utilizes an enhanced transformer network to generate high-resolution triplanes, which are 3D volumetric representations from the input image. This network is optimized to handle larger resolutions efficiently, capturing finer details and reducing aliasing artifacts
UV-Unwrapping and Texturing
The model generates UV-unwrapped, textured 3D meshes, making the assets ready for use in various applications such as game engines and rendering work. It also includes a delighting step to remove low-frequency illumination effects, ensuring the meshes can be used under different lighting conditions
Material and Illumination Estimation
The model predicts global metallic and roughness values, enhancing the reflective behaviors during rendering. This approach improves the visual quality and consistency of the generated 3D assets
