DiffFAS: Face Anti-Spoofing via Generative Diffusion Models
Xinxu Ge, Xin Liu, Zitong Yu +4
Face anti-spoofing (FAS) plays a vital role in preventing face recognition (FR) systems from presentation attacks. Nowadays, FAS systems face the challenge of domain shift, impacti…
Multi-scale multi-modal micro-expression recognition algorithm based on transformer
Fengping Wang, Jie Li, Chun Qi +2
A micro-expression is a spontaneous unconscious facial muscle movement that can reveal the true emotions people attempt to hide. Although manual methods have made good progress and…
Reconstruction of compressed spectral imaging based on global structure and spectral correlation
Pan Wang, Jie Li, Jieru Chen +2
In this paper, a convolutional sparse coding method based on global structure characteristics and spectral correlation is proposed for the reconstruction of compressive spectral im…
A Dynamic 3D Spontaneous Micro-expression Database: Establishment and Evaluation
Fengping Wang, Jie Li, Siqi Zhang +3
Micro-expressions are spontaneous, unconscious facial movements that show people's true inner emotions and have great potential in related fields of psychological testing. Since th…
CNN Retrieval based Unsupervised Metric Learning for Near-Duplicated Video Retrieval
Hao Cheng, Ping Wang, Chun Qi
As important data carriers, the drastically increasing number of multimedia videos often brings many duplicate and near-duplicate videos in the top results of search. Near-duplicat…
