A Survey of Automatic Facial Micro-expression Analysis: Databases, Methods and Challenges
Yee-Hui Oh, John See, Anh Cat Le Ngo +2
Over the last few years, automatic facial micro-expression analysis has garnered increasing attention from experts across different disciplines because of its potential application…
Enriched Long-term Recurrent Convolutional Network for Facial Micro-Expression Recognition
Huai-Qian Khor, John See, Raphael C. W. Phan +1
Facial micro-expression (ME) recognition has posed a huge challenge to researchers for its subtlety in motion and limited databases. Recently, handcrafted techniques have achieved…
Spontaneous Subtle Expression Detection and Recognition based on Facial Strain
Sze-Teng Liong, John See, Raphael Chung-Wei Phan +4
Optical strain is an extension of optical flow that is capable of quantifying subtle changes on faces and representing the minute facial motion intensities at the pixel level. This…
Sparsity in Dynamics of Spontaneous Subtle Emotions: Analysis \& Application
Anh Cat Le Ngo, John See, Raphael Chung-Wei Phan
Spontaneous subtle emotions are expressed through micro-expressions, which are tiny, sudden and short-lived dynamics of facial muscles; thus poses a great challenge for visual reco…
