Facial Expression Hallucination
2005 Seventh IEEE Workshops on Applications of Computer Vision (WACV/MOTION'05) - Volume 1, 2005Given a person's neutral face image, we can predict his/her expressive face images by machine learning techniques. Different from the prior expression cloning or image analogy approaches, we try to hallucinate the person's plausible facial expression with the help of a face expression database.

How to build virtual agents that establish rapport with human? According to Tickle-Degnen and Rosenthal [4], the three essential components of rapport are mutual attentiveness, positivity and coordination. In our previous work, we designed an embodied virtual agent to establish rapport with a human speaker by providing rapid and contingent nonverbal ...

Facial Reactions to Facial Expressions
Psychophysiology, 1982ABSTRACTPrevious research has demonstrated that different patterns of facial muscle activity are correlated with different emotional states. In the present study subjects were exposed to pictures of happy and angry facial expressions, in response to which their facial electromyographic (EMG) activities, heart rate (HR), and palmar skin conductance ...

Facial expression is usually synthesized or predicted on the basis of a given emotion. The prototypical expressions for basic emotions (happiness, sadness, surprise, disgust, anger, and fear) as postulated by discrete emotion psychologists are rather consistently produced and interpreted among different cultures, and can be used as icons to represent a

This study examined facial expression in the presentation of sarcasm. 60 responses (sarcastic responses = 30, nonsarcastic responses = 30) from 40 different speakers were coded by two trained coders. Expressions in three facial areas—eyebrow, eyes, and mouth—were evaluated. Only movement in the mouth area significantly differentiated ratings of sarcasm

Facial expression decomposition
Proceedings Ninth IEEE International Conference on Computer Vision, 2003In this paper, we propose a novel approach for facial expression decomposition - higher-order singular value decomposition (HOSVD), a natural generalization of matrix SVD. We learn the expression subspace and person subspace from a corpus of images showing seven basic facial expressions, rather than resort to expert-coded facial expression parameters ...

Caricaturing facial expressions
Cognition, 2000The physical differences between facial expressions (e.g. fear) and a reference norm (e.g. a neutral expression) were altered to produce photographic-quality caricatures. In Experiment 1, participants rated caricatures of fear, happiness and sadness for their intensity of these three emotions; a second group of participants rated how 'face-like' the ...

SUMMARY People in pain communicate their experience via facial expressions. There has been considerable research into the properties of pain expressions. This article reviews basic findings on the encoding and decoding of pain expression. The facial expression of pain is characterized and recent findings on its assessment and psychometric properties ...

The paper aims at recognizing the various human facial expressions. Every countenance is marked by changes in the feature points of the face. These feature points are located in various regions of the face. There are two phases in the facial expression recognition technique described here.

We propose the concept of manifold of facial expression based on the observation that images of a subject's facial expressions define a smooth manifold in the high dimensional image space. Such a manifold representation can provide a unified framework for facial expression analysis.
