Joint Physical-Digital Facial Attack Detection Via Simulating Spoofing Clues

2 code implementations12 Apr 2024 Xianhua He, Dashuang Liang, Song Yang, Zhanlong Hao, Hui Ma, Binjie Mao, Xi Li, Yao Wang, Pengfei Yan, Ajian Liu

SPSC and SDSC augment live samples into simulated attack samples by simulating spoofing clues of physical and digital attacks, respectively, which significantly improve the capability of the model to detect "unseen" attack types.

CustomListener: Text-guided Responsive Interaction for User-friendly Listening Head Generation

no code implementations1 Mar 2024 Xi Liu, Ying Guo, Cheng Zhen, Tong Li, Yingying Ao, Pengfei Yan

To achieve coherence between segments, we design a Past Guided Generation Module (PGG) to maintain the consistency of customized listener attributes through the motion prior, and utilize a diffusion-based structure conditioned on the portrait token and the motion prior to realize the controllable generation.

Cooperation Does Matter: Exploring Multi-Order Bilateral Relations for Audio-Visual Segmentation

1 code implementation11 Dec 2023 Qi Yang, Xing Nie, Tong Li, Pengfei Gao, Ying Guo, Cheng Zhen, Pengfei Yan, Shiming Xiang

For the first time, our framework explores three types of bilateral entanglements within AVS: pixel entanglement, modality entanglement, and temporal entanglement.

LatentWarp: Consistent Diffusion Latents for Zero-Shot Video-to-Video Translation

no code implementations1 Nov 2023 Yuxiang Bao, Di Qiu, Guoliang Kang, Baochang Zhang, Bo Jin, Kaiye Wang, Pengfei Yan

As a result, the corresponding regions across the adjacent frames can share closely-related query tokens and attention outputs, which can further improve latent-level consistency to enhance visual temporal coherence of generated videos.

Controllable Guide-Space for Generalizable Face Forgery Detection

no code implementations ICCV 2023 Ying Guo, Cheng Zhen, Pengfei Yan

In this paper, we propose a controllable guide-space (GS) method to enhance the discrimination of different forgery domains, so as to increase the forgery relevance of features and thereby improve the generalization.

Learn to Cluster Faces via Pairwise Classification

no code implementations ICCV 2021 Junfu Liu, Di Qiu, Pengfei Yan, Xiaolin Wei

However, they usually suffer from excessive memory consumption especially on large-scale graphs, and rely on empirical thresholds to determine the connectivities between samples in inference, which restricts their applications in various real-world scenes.
