AI Technical Summary
Conventional 3D Gaussian splatting-based avatar generation models face issues with 3D Gaussians becoming separated from the movement of FLAME meshes, leading to defects when generating unseen movements, particularly in training distributions.
A model that accurately assigns 3D Gaussians to corresponding mesh regions by normalizing the angle and position of the Gaussians, classifying faces into first and second sets based on reconstructible geometric structure, and incorporating internal mouth components and vertex offsets to enhance mesh accuracy.
Enables accurate assignment of 3D Gaussians to mesh regions, improving the generation of high-quality textures and animations, particularly in unseen movements, with reduced defects and enhanced geometric structure representation.
