Automatic facial expression analysis
… of our emotionally expressive behaviour. We use facial expressions to display our emotional states and to manage our interactions. Furthermore, we express and read emotions in faces effortlessly. However, automatic understanding of facial expressions is a very difficult task computationally, …

Image-based facial expression recognition
This work deals with facial expression recognition from various face representations. The key contributions of the work are both empirical and theoretical. In empirical work, we first design and successfully test a framework for near-frontal expression recognition. Then we do a significance …

Facial Expression Cloning with Fuzzy Membership Functions
… results of a system to explore cloning of facial expressions between dissimilar face models, so new faces can be animated using the animations from existing faces. The system described in this thesis uses fuzzy membership functions and subtractive clustering to represent faces and …

Verification of emotion recognition from facial expression
Analysis of facial expressions is an active topic of research with many potential applications, since the human face plays a significant role in conveying a person's mental state. Due to the practical values it brings, scientists and researchers from different fields such as psychology, finance, …

Facial expression recognition for a sociable robot
… to them accordingly. In this thesis, I present a facial expression system that recognizes the facial features of human subjects in an unsupervised manner and interprets the facial expressions of the individuals. The facial expression system is integrated with an existing emotional model for the …

Personalized machine learning for facial expression analysis
… of deep convolutional networks for facial expression analysis. While prior work focused on population-based ("one-size-fits-all") models for prediction of affective states (valence/arousal), I constructed personalized versions of these models to improve upon state-of-the-art general …

Facial Expression Recognition and Interpretation in Shy Children
… we examined the relation between shyness and facial expression processing in children. In Study 1, facial expression recognition was examined by asking 97 children ages 12 to 14 years to identify six different expressions displayed at 50% and 100% intensity, as well as a neutral expression. In …

Facial Expression Discrimination in Adults Experiencing Posttraumatic Stress Symptoms
… adults’ ability to discriminate between various facial expressions of emotions. Additionally, the study examined whether individuals reporting PTSS exhibited an attentional bias toward threat-related facial expressions of emotions. The research design was a 2 (expression intensity) x 3 (emotional …

Cortical Control of Naturalistic Facial Expression Production in Primates
<p>Facial expressions constitute a fundamental class of social communication signals in primates. Nonverbal expressions shared between individuals can instantly and effortlessly communicate endogenous affective state, the valence of external stimuli, as well as more complex concepts such as …

3-D facial expression representation using statistical shape models
Facial expressions are visible signs of person's affective state, cognitive activity and personality. Automatic recognition of facial expressions is an important component for a wide spectrum of applications including human-computer interfaces, video conferencing, augmented reality and human …

Automatic real-time facial expression recognition for signed language translation
… and computational efficiency of automatic facial expression recognition. In particular, we compared a local segmentation of the face around the mouth, eyes, and brows to a global segmentation of the whole face. Our results indicated that, surprisingly, classifying features from the whole …

Evaluating Consumer Emotional Response to Beverage Sweeteners through Facial Expression Analysis
… term questionnaire (explicit), and automated facial expression analysis (AFEA) (implicit). Facial expression responses and emotion term categorization based on selection frequencies were able to adequately discern differences in emotional response as it related to hedonic liking between …

Robust facial expression recognition in the presence of rotation and partial occlusion
This research proposes an approach to recognizing facial expressions in the presence of rotations and partial occlusions of the face. The research is in the context of automatic machine translation of South African Sign Language (SASL) to English. The proposed method is able to accurately recognize …

DEEP LEARNING FOR FOR LARGE-SCALE FACIAL EXPRESSION RECOGNITION IN THE WILD
Human facial expression recognition (FER) is a challenging task due to ambiguous facial expressions and highly skewed, imbalanced datasets. Even with recent advances in deep learning, these obstacles still remain. Facial expressions are commonly assigned discrete emotions, as per the categorical …
