Convolutional neural network based face forgery detection methods have achieved remarkable results during training, but struggled to maintain comparable performance during testing.

DH-AUG: DH Forward Kinematics Model Driven Augmentation for 3D Human Pose Estimation

1 code implementation19 Jul 2022 Linzhi Huang, Jiahao Liang, Weihong Deng

To solve this problem, we propose a pose augmentation solution via DH forward kinematics model, which we call DH-AUG. We observe that the previous work is all based on single-frame pose augmentation, if it is directly applied to video pose estimator, there will be several previously ignored problems: (i) angle ambiguity in bone rotation (multiple solutions); (ii) the generated skeleton video lacks movement continuity.

Identifying Rhythmic Patterns for Face Forgery Detection and Categorization

no code implementations4 Jul 2022 Jiahao Liang, Weihong Deng

Motivated by this key observation, we propose a framework for face forgery detection and categorization consisting of: 1) a Spatial-Temporal Filtering Network (STFNet) for PPG signals filtering, and 2) a Spatial-Temporal Interaction Network (STINet) for constraint and interaction of PPG signals.
