Facial analysis in video : detection and recognition
… characteristics. Among these biometrics, facial patterns have the major advantage of being the least intrusive. Automatic face recognition systems thus have great potential in a wide spectrum of application areas. Focusing on facial analysis, this dissertation presents a face detection …

Facial Analysis From Continuous Video With Application to Human -Computer Interface
… described in this thesis for embedded face and facial expression recognition is based on a novel probabilistic framework. In this novel framework, faces are modeled not only by their appearance, but also by the spatio-temporal deformation pattern of their expressions. Face recognition and facial …

The impact of context on expressed vs. self-reported emotion: An alcohol-administration facial analysis trial
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

Towards trainable man-machine interfaces : combining top-down constraints with bottom-up learning in facial analysis
… We investigate these questions in the realm of facial analysis. We propose the use of a linear morphable model (LMM) for representing top-down structure and use it to model various facial variations such as mouth shapes and expression, the pose of faces and visual speech (visemes). We apply a …

Non-Invasive Techniques for the Detection and Diagnosis of Dementia
… at measurements of (i) postural stability (ii) facial analysis and (iii) fully-immersive virtual reality in cognitively-healthy individuals. These techniques were chosen as postural stability and facial analysis change in dementia and whilst virtual reality has previously been used in dementia …

3D face modeling with a consumer depth camera
… for face models include computer animation and facial analysis. Over the past few decades, several face modeling techniques have been developed using both active and passive sensors. Unlike passive sensors, which reconstruct the geometry of the face using reflected ambient light, active sensors …

Use of a wearable camera system in conversation : toward a companion tool for social-emotional learning in autism
… learn how you look to others. Video playback and analysis tools can also be used to review and learn how others wearing the Self-Cam express themselves to you. We are developing a tool to teach the kind of facial analysis that an empathetic person might notice in interpretation of everyday …

Measuring Consumer Emotional Response to Tastes and Foods through Facial Expression Analysis
… specifically emotion questionnaire ballots and facial expression analysis, as compared to conventional sensory methods in developing a holistic view of product interest and engagement. Emotional response to 1% low-fat unflavored and chocolate-flavored milk was evaluated by using an emotion-based …

Analysis of Human Face Shape Abnormalities Using Machine Learning
Because the capture of 3D facial form for people with medical conditions has become a practical reality, much research has been done using computer-based automatic methods to study 3D facial characteristics. This study focuses on face abnormality, especially, children with cleft lip and/or palate. …

On a three-dimensional gait recognition system
… dependence - a serious problem for many gait analysis approaches. <br/><br/>The early prototype by Middleton et al. was used as the basis for creating a new and improved system, designed for the collection of a new large dataset, containing gait, face and ear. Extensive modifications were …

Reconstruction of three-dimensional facial geometric features related to fetal alcohol syndrome using adult surrogates
… evidence of growth abnormalities and abnormal facial features. Direct anthropometry has traditionally been used to obtain facial data to assess the FAS facial features. Research efforts have focused on indirect anthropometry such as 3D surface imaging systems to collect facial data for facial …

Transformative Science Education Through Action Research And Self-Study Practices
… and associated methods for research on facial expression of emotion. I use a facial action coding system developed by Paul Ekman in the 1970s (Ekman, 2002) to study facial representation of emotions. In chapters 4 and 5, I review the history of oximetry and ways in which an oximeter can …
