Abstract:

Facial expression recognition has become an active research topic in recent years due to its applications in human computer interfaces and data-driven animation. In this thesis, we focus on the problem of how to e?ectively use domain, temporal and categorical information of facial expressions to help computer understand human emotions. Over the past decades, many techniques (such as neural networks, Gaussian processes, support vector machines, etc.) have been applied to facial expression analysis. Recently graphical models have emerged as a general framework for applying probabilistic mo

Abstract:

The experiments investigate the functional relationship between the processing of facial identity, emotional expression and facial speech. They were designed in order to further explore a widely accepted model of parallel, independent face perception components (Bruce and Young, 1986), which has been challenged recently (e.g. Walker et. al., 1995; Yakel et. al., 2000; Schweinberger et. al., 1998; Schweinberger et.al., 1999). In addition to applying a selective attention paradigm (Garner, 1974; 1976), dependencies between face related processes are explored by morphing, a digital graphic editin

Abstract:

Psychiatric patients, particularly schizophrenics, tend to be less accurate decoders of facial expressions than normals. The involvement of three basic information processing stages in this deficit was investigated: attention; encoding; and processing. Psychiatric inpatients, classified by diagnosis and severity of pathology, and nonpatient controls were administered seven facial cue decoding tasks. Orientation of attention was assessed through rate of diversion of gaze from the stimuli. Encoding was assessed using simple tasks, requiring one contrast of two facial stimuli and selection from t

Abstract:

A range of research has shown an advantage for the perception of faces from same-race compared to other-races – the other race effect (ORE). Nevertheless, previous studies have focused on the ability to recognize facial identity. This thesis focuses on how information from the face that conveys expression is processed in own-race and other-race faces. First, the cross-cultural processing of facial expressions of basic emotions in Western Caucasian and Chinese observers was investigated. Perceptual judgments of facial expressions were quite similar between cultural groups, but facial expression

This thesis investigates the hypothesis that emotions play an influential role in cognition. Interference between facial emotional expression processing and selected tasks is measured using a variety of experimental methods. Prior to the main experimental chapters, the collection and assessment (Chapter 2, Exp. 1) of stimulus materials is described. Experiments 2-11 then concentrate on the likelihood of interference with other types of information from the face. Findings using a Garner design suggest that, although identity processing may be independent of expression variation, expression proc

Two studies were conducted in which 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 Study 2, the focus shifted from the recognition of emotions to the interpretation of emotions. In this study, 123 children aged 12 to 14 years were asked a series of questions regarding how they would perceive different facial expressions. Findings from Study 1 showed

In Experiments One to Four, unfamiliar face recognition was investigated using identical numbers of frames in the learning phase; these were viewed as a series of static images, or in moving sequences (using computer animation). There was no additional benefit from studying the moving sequences, but signal detection measurements showed an advantage for using dynamic sequences at test. In Experiments Five and Six, moving and static images of unfamiliar faces were matched for expression or identity. Without prior stud

Abstract:

Real-world perception of emotion results from the integration of multiple cues, most notably facial expression and affective prosody. The use of incongruent emotional stimuli presents an opportunity to study the interaction between sensory modalities. Thirty-seven participants were exposed to audio-visual stimuli (Robins & Schultz, 2004) including angry, fearful, happy, and neutral presentations. Eighty stimuli contain matching emotions and 240 contain incongruent emotional cues. Matching emotions elicited a significant number of correct responses for all four emotions.

Abstract:

Current theoretical models of face recognition assume a functional dissociation of the processing of facial identity and expression. This assumption was investigated using a combination of event-related potential (ERP) and behavioural techniques which involved comparison of sequentially presented photographs of faces. In all studies ERPs were recorded from frontal, temporal and parietal sites on both hemispheres. In the first study the effect of familiarity on identity judgements was investigated. The three main observations were: 1) Processing of unfamiliar faces was associated with a widespr

Multi-player on-line games (MOGs) have become increasingly popular because of the opportunity they provide for collaboration, communications and interactions. However, compared with ordinary human communication, MOG still has several limitations, especially in the communication using facial expressions. Although detailed facial animation has already been achieved in a number of MOGs, players have to use text commands to control the expressions of avatars.

Conversely, the healthy controls (HC) were shown to selectively attend to happy faces. At recognition memory testing, DP did not exhibit a memory bias for depression-rel

This thesis examines the way in which meaningful facial signals (i.e., eye gaze and emotional facial expressions) influence the allocation of visual attention. These signals convey information about the likely imminent behaviour of the sender and are, in turn, potentially relevant to the behaviour of the viewer. It is already well established that different signals influence the allocation of attention in different ways that are consistent with their meaning. For example, direct gaze (i.e., gaze directed at the viewer) is considered both to draw attention to its location and hold attention whe

The facial width-to-height ratio (fWHR) is a measure of the cheekbone width divided by the height of the face from the upper lip to the brows.

The fWHR is suggested to subtly resemble angry facial expressions, which, in turn, also signal threat.

Abstract:

Facial expression recognition (FER) is still a challenging concept, and machines struggle to comprehend effectively the dynamic shifts in facial expressions of human emotions. The existing systems, which have proven to be effective, consist of deeper network structures that need powerful and expensive hardware. The deeper the network is, the longer the training and the testing. Many systems use expensive GPUs to make the process faster. To remedy the above challenges while maintaining the main goal of improving the accuracy rate of the recognition, we create a generic hierarchical struct
