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…
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…
Multi-scale Visual Attention & Saliency Modelling with Decision Theory
Anh Cat Le Ngo, Li-Minn Ang, Guoping Qiu +1
Bottom-up saliency, an early human visual processing, behaves like binary classification of interest and null hypothesis. Its discriminant power, mutual information of image featur…
Fast non parametric entropy estimation for spatial-temporal saliency method
Anh Cat Le Ngo, Guoping Qiu, Geoff Underwood +2
This paper formulates bottom-up visual saliency as center surround conditional entropy and presents a fast and efficient technique for the computation of such a saliency map. It is…
Multiscale Discriminant Saliency for Visual Attention
Anh Cat Le Ngo, Kenneth Ang Li-Minn, Guoping Qiu +1
The bottom-up saliency, an early stage of humans' visual attention, can be considered as a binary classification problem between center and surround classes. Discriminant power of…
