Can Protective Watermarking Safeguard the Copyright of 3D Gaussian Splatting?

AAAI 2026technical

3D Gaussian Splatting (3DGS) has emerged as a powerful representation for 3D scenes, widely adopted due to its exceptional efficiency and high-fidelity visual quality. Given the significant value of 3DGS assets, recent works have introduced specialized watermarking schemes to ensure copyright protec

Splats in Splats: Robust and Effective 3D Steganography Towards Gaussian Splatting

AAAI 2026technical

3D Gaussian splatting (3DGS) has demonstrated impressive 3D reconstruction performance with explicit scene representations. Given the widespread application of 3DGS in 3D reconstruction and generation tasks, there is an urgent need to protect the copyright of 3DGS assets. However, existing copyright

SpikeGS: Reconstruct 3D Scene Captured by a Fast-Moving Bio-Inspired Camera

AAAI 2025technical

3D Gaussian Splatting (3DGS) has been proven to exhibit exceptional performance in reconstructing 3D scenes. However, the effectiveness of 3DGS heavily relies on sharp images, and fulfilling this requirement presents challenges in real-world scenarios particularly when utilizing fast-moving cameras.…

VOODOO 3D: Volumetric Portrait Disentanglement For One-Shot 3D Head Reenactment

CVPR 2024poster

We present a 3D-aware one-shot head reenactment method based on a fully volumetric neural disentanglement framework for source appearance and driver expressions. Our method is real-time and produces high-fidelity and view-consistent output suitable for 3D teleconferencing systems based on holographi…

Learning To Listen: Modeling Non-Deterministic Dyadic Facial Motion

CVPR 2022poster

We present a framework for modeling interactional communication in dyadic conversations: given multimodal inputs of a speaker, we autoregressively output multiple possibilities of corresponding listener motion. We combine the motion and speech audio of the speaker using a motion-audio cross attentio…

Normalized Avatar Synthesis Using StyleGAN and Perceptual Refinement

CVPR 2021poster

We introduce a highly robust GAN-based framework for digitizing a normalized 3D avatar of a person from a single unconstrained photo. While the input image can be of a smiling person or taken in extreme lighting conditions, our method can reliably produce a high-quality textured model of a person's…

HairNet: Single-View Hair Reconstruction using Convolutional Neural Networks

ECCV 2018poster

We introduce a deep learning-based method to generate full 3D hair geometry from an unconstrained image. Our method can recover local strand details and has real-time performance. State-of-the-art hair modeling techniques rely on large hairstyle collections for nearest neighbor retrieval and then pe…

Real-Time Hair Rendering using Sequential Adversarial Networks

ECCV 2018poster

We present an adversarial network for rendering photorealistic hair as an alternative to conventional computer graphics pipelines. Our deep learning approach does not require low-level parameter tuning nor ad-hoc asset design. Our method simply takes a strand-based 3D hair model as input and provide…

Photorealistic Facial Texture Inference Using Deep Neural Networks

CVPR 2017spotlight

We present a data-driven inference method that can synthesize a photorealistic texture map of a complete 3D face model given a partial 2D view of a person in the wild. After an initial estimation of shape and low-frequency albedo, we compute a high-frequency partial texture map, without the shading…
