GaussianSpeech: Audio-Driven Personalized 3D Gaussian Avatars

ICCV 2025poster

We introduce GaussianSpeech, a novel approach that synthesizes high-fidelity animation sequences of photorealistic and personalized multi-view consistent 3D human head avatars from spoken audio at real-time rendering rates. To capture the expressive and detailed nature of human heads, including skin…

FaceTalk: Audio-Driven Motion Diffusion for Neural Parametric Head Models

CVPR 2024poster

We introduce FaceTalk a novel generative approach designed for synthesizing high-fidelity 3D motion sequences of talking human heads from input audio signal. To capture the expressive detailed nature of human heads including hair ears and finer-scale eye movements we propose to couple speech signal…

COSMOS: Catching Out-of-Context Image Misuse Using Self-Supervised Learning

AAAI 2023technical

Despite the recent attention to DeepFakes, one of the most prevalent ways to mislead audiences on social media is the use of unaltered images in a new but false context. We propose a new method that automatically highlights out-of-context image and text pairs, for assisting fact-checkers. Our key in…

TAFIM: Targeted Adversarial Attacks against Facial Image Manipulations

ECCV 2022poster

"Face manipulation methods can be misused to affect an individual’s privacy or to spread disinformation. To this end, we introduce a novel data-driven approach that produces image-specific perturbations which are embedded in the original images. The key idea is that these protected images prevent fa…
