Modelling facial action units using partial differential equations.
… thesis 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 …

Identifying facial landmarks, action units and emotions using deep networks
… Convolutional Neural 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 …

The computational face for facial emotion analysis: Computer based emotion analysis from the face
Facial expressions are considered to be the most revealing way of understanding the human psychological state during face-to-face communication. It is believed that a more natural interaction between humans and machines can be undertaken through the detailed understanding of the different facial …

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 …

Automated Rat Grimace Scale for the Assessment of Pain
… rat grimace 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 …

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 …

FACIAL EXPRESSION DISCRIMINATES BETWEEN PAIN AND ABSENCE OF PAIN IN THE NON-COMMUNICATIVE, CRITICALLY ILL ADULT PATIENT
… paralyzed or mechanically ventilated) patient. Facial expressions are considered among the most reflexive and automatic nonverbal indices of pain. The facial expression component of pain assessment tools include a variety of facial descriptors (wincing, frowning, grimacing, smile/relaxed) with …
