High Fidelity Head Avatar

High-fidelity head avatar creation aims to generate realistic, animatable 3D models of human heads from various input data, such as videos or images. Current research emphasizes efficient rendering speeds and high-quality results, employing diverse model architectures including neural radiance fields (NeRFs), mesh-based models, and Gaussian-based representations, often combined with techniques like 3D Morphable Models (3DMMs) for improved accuracy and control. These advancements are driving progress in augmented and virtual reality applications, telepresence systems, and digital content creation, offering increasingly realistic and interactive virtual representations of individuals.
