Apex-Centered Spatio-Temporal Rank Pooling and Gradient Attention for Micro-Expression Recognition
Luu Tu Nguyen, Vu Tram Anh Khuong, Thanh Ha Le +1
Micro-expression recognition (MER) is a challenging task due to the subtle and fleeting nature of micro-expressions. Traditional input modalities, such as Apex Frame, Optical Flow,…
Dual-View Optical Flow for 4D Micro-Expression Recognition - A Multi-Stream Fusion Attention Approach
Luu Tu Nguyen, Thi Bich Phuong Man, Vu Tram Anh Khuong +2
Micro-expression recognition is vital for affective computing but remains challenging due to the extremely brief, low-intensity facial motions involved and the high-dimensional nat…
A Novel Combined Optical Flow Approach for Comprehensive Micro-Expression Recognition
Vu Tram Anh Khuong, Thi Bich Phuong Man, Luu Tu Nguyen +2
Facial micro-expressions are brief, involuntary facial movements that reveal hidden emotions. Most Micro-Expression Recognition (MER) methods that rely on optical flow typically fo…
Improving Micro-Expression Recognition with Phase-Aware Temporal Augmentation
Vu Tram Anh Khuong, Luu Tu Nguyen, Thanh Ha Le +1
Micro-expressions (MEs) are brief, involuntary facial movements that reveal genuine emotions, typically lasting less than half a second. Recognizing these subtle expressions is cri…
FMANet: A Novel Dual-Phase Optical Flow Approach with Fusion Motion Attention Network for Robust Micro-expression Recognition
Luu Tu Nguyen, Vu Tram Anh Khuong, Thi Bich Phuong Man +2
Facial micro-expressions, characterized by their subtle and brief nature, are valuable indicators of genuine emotions. Despite their significance in psychology, security, and behav…
DIANet: A Phase-Aware Dual-Stream Network for Micro-Expression Recognition via Dynamic Images
Vu Tram Anh Khuong, Luu Tu Nguyen, Thi Bich Phuong Man +2
Micro-expressions are brief, involuntary facial movements that typically last less than half a second and often reveal genuine emotions. Accurately recognizing these subtle express…
