TALL: Thumbnail Layout for Deepfake Video Detection

1 code implementation ICCV 2023 Yuting Xu, Jian Liang, Gengyun Jia, Ziming Yang, Yanhao Zhang, Ran He

This paper introduces a simple yet effective strategy named Thumbnail Layout (TALL), which transforms a video clip into a pre-defined layout to realize the preservation of spatial and temporal dependencies.

Masked Relation Learning for DeepFake Detection

2 code implementations 2023 2023 Ziming Yang, Jian Liang, Yuting Xu, Xiao-Yu Zhang, Ran He

A relation learning module masks partial correlations between regions to reduce redundancy and then propagates the relational information across regions to capture the irregularity from a global view of the graph.

Heterogeneous Face Recognition via Face Synthesis with Identity-Attribute Disentanglement

no code implementations10 Jun 2022 Ziming Yang, Jian Liang, Chaoyou Fu, Mandi Luo, Xiao-Yu Zhang

Secondly, we devise a face synthesis module (FSM) to generate a large number of images with stochastic combinations of disentangled identities and attributes for enriching the attribute diversity of synthetic images.
