Abstract:

>Magister Scientiae - MSc<br>The South African Sign Language research group at the University of the Western Cape is in the process of creating a fully-edged machine translation system to automatically translate between South African Sign Language and English. A major component of the system is the ability to accurately recognise facial expressions, which are used to convey emphasis, tone and mood within South African Sign Language sentences. Traditionally, facial expression recognition research has taken one of two paths: either recognising whole facial expressions of which there are six i.e.

Abstract:

Desde la esfera de las Bellas Artes, las emociones manifestadas por el ser humano han sido un territorio complejo y de gran interés. Prueba de ello, lo tenemos con los estudios de dibujantes, anatomistas y fisiólogos desde el siglo XV hasta nuestros días. En nuestro ámbito, tenemos constancia de muchos estudios y tratados interdisciplinares que intentan codificar y entender desde lo más objetivo el análisis de las emociones. En este proyecto de investigación doctoral, pretendemos analizar exhaustivamente desde el dibujo, un método que proviene del ámbito de la psicología y que creemos que nece

Abstract:

Det här examensarbetet undersöker om ett anatomiskt system framtaget för att kategorisera ansiktsrörelser inom psykologisk forskning kan anpassas på en ansiktsrigg för att effektivare kunna framställa ansiktsanimation för datorspel. Rapporten beskriver varför Facial Action Coding System skapades, hur det används samt tar upp olika sammanhang som systemet tidigare använts för. Rapporten beskriver det praktiska arbetet för att konstruera en ansiktsrigg ämnat för datorspel och diskuterar skillnader mellan att rigga för datorspel och film. Examensarbetet beskriver klassiska användbarhetsprinciper

Abstract:

Sensory and consumer sciences seek to comprehend the influences of sensory perception on consumer behaviors such as product liking and purchase. The food industry assesses product liking through hedonic testing but often does not capture affectual response as it pertains to product-generated (PG) and product-associated (PA) emotions. This research sought to assess the application of PA and PG emotion methodology to better understand consumer experiences. A systematic review of the existing literature was performed that focused on the Facial Action Coding System (FACS) and its use to investigat

Abstract:

Philosophiae Doctor - PhD<br>This research investigated the application of recurrent neural networks (RNNs) for recognition of facial expressions based on facial action coding system (FACS). Support vector machines (SVMs) were used to validate the results obtained by RNNs. In this approach, instead of recognizing whole facial expressions, the focus was on the recognition of action units (AUs) that are defined in FACS. Recurrent neural networks are capable of gaining knowledge from temporal data while SVMs, which are time invariant, are known to be very good classifiers. Thus, the research cons

Abstract:

Facial expressions convey a wealth of information about our feelings, personality and mental state. In this thesis we seek efficient ways of representing and analysing facial expressions of varying intensities. Firstly, we analyse state-of-the-art systems by decomposing them into their fundamental components, in an effort to understand what are the useful practices common to successful systems. Secondly, we address the problem of sequence registration, which emerged as an open issue in our analysis. The encoding of the (non-rigid) motions generated by facial expressions is facilitated when the

Abstract:

The aim of this study is to present a novel three dimensional (3D) facial animation method for morphing emotions and facial expressions from one face model to another. For this purpose, smooth and realistic face models were animated with thin plate splines (TPS). Neutral face models were animated and compared with the actual expressive face models. Neutral and expressive face models were obtained from subjects via a 3D face scanner. The face models were preprocessed for pose and size normalization. Then muscle and wrinkle control points were located to the source face with neutral expression a

Abstract:

BACKGROUND: Pain assessment is a significant challenge in critically ill adults, especially those unable to communicate their pain level. At present there is no universally accepted pain scale for use in the non-communicative (cognitively impaired, sedated, 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 inconsistent pain intensity ratings or checklis

We present a set of easy-to-use methods and tools to analyze human attention, behaviour, and physiological responses. A potential application of our work is evaluating user interfaces being used in a natural manner. Our approach is designed to be scalable and to work remotely on regular personal computers using expensive and noninvasive equipment. The data sources our tool processes are nonintrusive, and captured from video; i.e. eye tracking, and facial expressions. For video data retrieval, we use a basic webcam.

Abstract:

The unprecedented turbulence and uncertainty experienced in global economic and financial markets because of the 'credit crunch' has had a damaging impact on consumer confidence. Trust and credibility have been eroded as many customers feel let down by the banks suggesting the need for banks to rebuild constructive dialogue and long-term, meaningful relationships with their customers again. Though financial service, in this case, is considered a utilitarian service, based on the fact that money is needed to support people‘s daily activities, the present state of financial service has suggested

Abstract:

No<br>In this paper we discuss a novel method of mathematically modelling facial action units for accurate representation of human facial expressions in 3- dimensions. Our method utilizes the approach of Facial Action Coding System (FACS). It is based on a boundary-value approach, which utilizes a solution to a fourth order elliptic Partial Differential Equation (PDE) subject to a suitable set of boundary conditions. Here the PDE surface generation method for human facial expressions is utilized in order to generate a wide variety of facial expressions in an efficient and realistic way.
