Learning Efficient Fuse-and-Refine for Feed-Forward 3D Gaussian Splatting

NeurIPS 2025poster

Recent advances in feed-forward 3D Gaussian Splatting have led to rapid improvements in efficient scene reconstruction from sparse views. However, most existing approaches construct Gaussian primitives directly aligned with the pixels in one or more of the input images. This leads to redundancies in…

Scaling Transformer-Based Novel View Synthesis with Models Token Disentanglement and Synthetic Data

ICCV 2025poster

Large transformer-based models have made significant progress in generalizable novel view synthesis (NVS) from sparse input views, generating novel viewpoints without the need for test-time optimization. However, these models are constrained by the limited diversity of publicly available scene datas…

MEGANE: Morphable Eyeglass and Avatar Network

CVPR 2023poster

Eyeglasses play an important role in the perception of identity. Authentic virtual representations of faces can benefit greatly from their inclusion. However, modeling the geometric and appearance interactions of glasses and the face of virtual representations of humans is challenging. Glasses and f…

NeuWigs: A Neural Dynamic Model for Volumetric Hair Capture and Animation

CVPR 2023poster

The capture and animation of human hair are two of the major challenges in the creation of realistic avatars for the virtual reality. Both problems are highly challenging, because hair has complex geometry and appearance, as well as exhibits challenging motion. In this paper, we present a two-stage…

RelightableHands: Efficient Neural Relighting of Articulated Hand Models

CVPR 2023poster

We present the first neural relighting approach for rendering high-fidelity personalized hands that can be animated in real-time under novel illumination. Our approach adopts a teacher-student framework, where the teacher learns appearance under a single point light from images captured in a light-s…

HVH: Learning a Hybrid Neural Volumetric Representation for Dynamic Hair Performance Capture

CVPR 2022poster

Capturing and rendering life-like hair is particularly challenging due to its fine geometric structure, complex physical interaction and the non-trivial visual appearance that must be captured. Yet, it is a critical component to create believable avatars. In this paper, we address the aforementioned…

Robust Egocentric Photo-Realistic Facial Expression Transfer for Virtual Reality

CVPR 2022poster

Social presence, the feeling of being there with a "real" person, will fuel the next generation of communication systems driven by digital humans in virtual reality (VR). The best 3D video-realistic VR avatars that minimize the uncanny effect rely on person-specific (PS) models. However, these PS mo…

Learning Compositional Radiance Fields of Dynamic Human Heads

CVPR 2021poster

Photorealistic rendering of dynamic humans is an important ability for telepresence systems, virtual shopping, synthetic data generation, and more. Recently, neural rendering methods, which combine techniques from computer graphics and machine learning, have created high-fidelity models of humans an…
