EAMM: One-Shot Emotional Talking Face via Audio-Based Emotion-Aware Motion Model

no code implementations30 May 2022 Xinya Ji, Hang Zhou, Kaisiyuan Wang, Qianyi Wu, Wayne Wu, Feng Xu, Xun Cao

Although significant progress has been made to audio-driven talking face generation, existing methods either neglect facial emotion or cannot be applied to arbitrary subjects.

Learning Hierarchical Cross-Modal Association for Co-Speech Gesture Generation

1 code implementation CVPR 2022 Xian Liu, Qianyi Wu, Hang Zhou, Yinghao Xu, Rui Qian, Xinyi Lin, Xiaowei Zhou, Wayne Wu, Bo Dai, Bolei Zhou

To enhance the quality of synthesized gestures, we develop a contrastive learning strategy based on audio-text alignment for better audio representations.

Sem2NeRF: Converting Single-View Semantic Masks to Neural Radiance Fields

1 code implementation21 Mar 2022 Yuedong Chen, Qianyi Wu, Chuanxia Zheng, Tat-Jen Cham, Jianfei Cai

In light of recent advances in NeRF-based 3D-aware generative models, we introduce a new task, Semantic-to-NeRF translation, that aims to reconstruct a 3D scene modelled by NeRF, conditioned on one single-view semantic mask as input.

Semantic-Aware Implicit Neural Audio-Driven Video Portrait Generation

no code implementations19 Jan 2022 Xian Liu, Yinghao Xu, Qianyi Wu, Hang Zhou, Wayne Wu, Bolei Zhou

Moreover, to enable portrait rendering in one unified neural radiance field, a Torso Deformation module is designed to stabilize the large-scale non-rigid torso motions.

AOT: Appearance Optimal Transport Based Identity Swapping for Forgery Detection

no code implementations NeurIPS 2020 Hao Zhu, Chaoyou Fu, Qianyi Wu, Wayne Wu, Chen Qian, Ran He

However, due to the lack of Deepfakes datasets with large variance in appearance, which can be hardly produced by recent identity swapping methods, the detection algorithm may fail in this situation.

Disentangled Representation Learning for 3D Face Shape

1 code implementation CVPR 2019 Zi-Hang Jiang, Qianyi Wu, Keyu Chen, Juyong Zhang

In this paper, we present a novel strategy to design disentangled 3D face shape representation.
