Relative Facial Action Unit Detection
Mahmoud Khademi, Louis-Philippe Morency
This paper presents a subject-independent facial action unit (AU) detection method by introducing the concept of relative AU detection, for scenarios where the neutral face is not…
Local Component Analysis for Nonparametric Bayes Classifier
Mahmoud Khademi, Mohammad T. Manzuri-Shalmani, Meharn safayani
The decision boundaries of Bayes classifier are optimal because they lead to maximum probability of correct decision. It means if we knew the prior probabilities and the class-cond…
Extended Two-Dimensional PCA for Efficient Face Representation and Recognition
Mehran Safayani, Mohammad T. Manzuri-Shalmani, Mahmoud Khademi
In this paper a novel method called Extended Two-Dimensional PCA (E2DPCA) is proposed which is an extension to the original 2DPCA. We state that the covariance matrix of 2DPCA is e…
Multilinear Biased Discriminant Analysis: A Novel Method for Facial Action Unit Representation
Mahmoud Khademi, Mehran Safayani, Mohammad T. Manzuri-Shalmani
In this paper a novel efficient method for representation of facial action units by encoding an image sequence as a fourth-order tensor is presented. The multilinear tensor-based e…
Recognizing Combinations of Facial Action Units with Different Intensity Using a Mixture of Hidden Markov Models and Neural Network
Mahmoud Khademi, Mohammad T. Manzuri-Shalmani, Mohammad H. Kiapour +1
Facial Action Coding System consists of 44 action units (AUs) and more than 7000 combinations. Hidden Markov models (HMMs) classifier has been used successfully to recognize facial…
Analysis, Interpretation, and Recognition of Facial Action Units and Expressions Using Neuro-Fuzzy Modeling
Mahmoud Khademi, Mohammad Hadi Kiapour, Mohammad T. Manzuri-Shalmani +1
In this paper an accurate real-time sequence-based system for representation, recognition, interpretation, and analysis of the facial action units (AUs) and expressions is presente…
Facial Expression Representation and Recognition Using 2DHLDA, Gabor Wavelets, and Ensemble Learning
Mahmoud Khademi, Mohammad H. Kiapour, Mehran Safayani +2
In this paper, a novel method for representation and recognition of the facial expressions in two-dimensional image sequences is presented. We apply a variation of two-dimensional…
