RGBAvatar – Reduced Gaussian Blendshapes for Online Modeling of Head Avatars

https://gapszju.github.io/RGBAvatar

A method for reconstructing photorealistic, animatable head avatars at speeds sufficient for on-the-fly reconstruction. Unlike prior approaches that utilize linear bases from 3D morphable models (3DMM) to model Gaussian blendshapes, our method maps tracked 3DMM parameters into reduced blendshape weights with an MLP, leading to a compact set of blendshape bases.
