Modelling facial action units using partial differential equations.
… discusses a novel method for modelling facial action units. It presents facial action units model based on boundary value problems for accurate representation of human facial expression in three-dimensions. In particular, a solution to a fourth order elliptic Partial Differential Equation (PDE) …

Identifying facial landmarks, action units and emotions using deep networks
… (CNNs) to predict facial landmarks, facial action units and emotions and to study the results of intermediate experiments while doing so. Learning the different features of facial images has always been a difficult task and primarily involves using hand-crafted features which would almost …

Judgment of feeling states from facial behavior: a bottom-up approach
… in themselves and judge in others. Individual action units, as scored by Ekman and Friesen's (1978) Facial Action Coding System (FACS), and selected combinations of action units were presented to observers in three pairs of studies. Filmstrip sequences were used in the first pair of studies, …

Automated Rat Grimace Scale for the Assessment of Pain
… scale (RGS) was developed based on facial action coding systems (FACS) which have known utility in non-verbal humans [6, 9]. The RGS measures facial action units of orbital tightening, ear changes, nose flattening, and whisker changes in an attempt to quantify the pain behaviors of the rat. …

Automatic real-time facial expression recognition for signed language translation
… We also developed a system for detecting FACS action units based on Haar features and the Adaboost boosting algorithm. This method achieves equally high recognition accuracy for certain AUs but operates two orders of magnitude more quickly than the Gabor+SVM approach. Finally, we developed a …

FACIAL EXPRESSION DISCRIMINATES BETWEEN PAIN AND ABSENCE OF PAIN IN THE NON-COMMUNICATIVE, CRITICALLY ILL ADULT PATIENT
… methods for interpreting the specific facial actions of pain in critically ill adults has not been identified. OBJECTIVE: The three specific aims of this prospective study were: 1) to describe facial actions during pain in non-communicative critically ill patients; 2) to determine facial …

The computational face for facial emotion analysis: Computer based emotion analysis from the face
… It is believed that a more natural interaction between humans and machines can be undertaken through the detailed understanding of the different facial expressions which imitate the manner by which humans communicate with each other. In this research, we study the different aspects of …

How deep learning can help emotion recognition
… the need for including the human during the interaction process has become more apparent. One simple way is to have the computer system understand and respond to the human's emotions. Previous works in emotion recognition have focused on improving performance by incorporating domain knowledge into …

The localist turn in EU Regional Policy viewed from a Tuscan Perspective
… in which regions are enrolled as self-contained action units, and are expected to compete against each other to secure their economic prosperity. Drawing on relational perspectives, I will contend that this approach is doubly problematic. From a substantive point of view, it leads to a …

Techniques for Facial Expression Recognition Using the Kinect
… involving psychology, human-computer interaction, health care, e-commerce, and many others. Although humans recognize facial expressions in a scene with little or no effort, reliable expression recognition by machine is still a challenging problem. Automatic facial expression recognition …

Spontaneous Facial Behavior Computing in Human Machine Interaction with Applications in Autism Treatment
… have affect-aware intelligent Human-Machine Interaction (HMI) systems, scientists and engineers have aimed to design interfaces which can emulate face-to-face communication. Such HMI systems are capable of detecting and responding upon users' emotions and affective states. One of the main …

Facial feature representation and recognition
… of emotion, cognitive processes, and social interaction. Facial expression representation and recognition have become a promising research area during recent years. Its applications include human-computer interfaces, human emotion analysis, and medical care and cure. In this dissertation, the …

FUNCTIONAL STATISTICAL LEARNING METHODS APPLIED TO HUMAN EMOTION RECOGNITION FROM FACIAL VIDEOS
… significant mean characteristics in grouped units and are further utilized as prior knowledge for multi-classification in a streamlined feature space, generating emotional agreement scores for incoming new samples. Both non-parametric and parametric multi-class classification methods are …

Creating Human-Like Facial Expressions Utilizing Artificial Muscles and Skin
… head. The method assumes that the origin of the action units are known prior and the underlying criterion in the design of faces being deformation of a soft elastomeric skin through tension in anchoring wires attached on one end to the sinking point and on the other to the actuator. Experimental …
