Nonverbal information, such as that contained in facial expressions, gestures, and tone of voice, plays an important role in human communications (Kurokawa, 1994). Facial expressions, especially, are a very important media for visually transmitting feelings and intentions (Yoshikawa, 2001; Uchida, 2006). At least one study has shown that more than half of all communication perceptions are trans...

Classical LBP such as complexity and high dimensions of feature vectors that make it necessary to apply dimension reduction processes. In this paper, we introduce an improved LBP algorithm to solve these problems that utilizes Fast PCA algorithm for reduction of vector dimensions of extracted features. In other words, proffer method (Fast PCA+LBP) is an improved LBP algorithm that is extracted ...

The six basic facial expressions (anger, disgust, fears, happy, sadness, surprise) which have been recognized in psychology are commonly used for facial expressions recognition research. In this work, we propose intuitive and effective facial features to recognize the six facial expressions by modifying the original facial feature points used by the original Active Appearance Model (AAM). The S...

BACKGROUND It has been hypothesized that the social dysfunction in social developmental disorders (SDDs), such as autism, Asperger disorder, and the socioemotional processing disorder, impairs the acquisition of normal face-processing skills. The authors investigated whether this purported perceptual deficit was generalized to both facial expression and facial identity or whether these differen...

In this paper, the facial expression is mainly focused to achieve the smooth tele-communications. The facial expressions has been considered as a most of the signi cant factors in tele-communications, such as tele-services. To realize the real time facial expression transportation system, we proposed the facial expression space (FES) and a correspondence technique between each personal facial e...

Facial expression analysis is an active area in human-computer interaction. Many techniques of facial expression analysis have been proposed that try to make the interaction tighter and more efficient. The essence of facial expression analysis is to recognize facial actions or to perceive human emotion through the changes of the face surface. Generally, there are three main steps in analyzing f...

Cross-cultural research on facial expression and the developments of methods to measure facial expression are briefly summarized. What has been learned about emotion from this work on the face is then elucidated. Four questions about facial expression and emotion are discussed: What information does an expression typically convey? Can there be emotion without facial expression? Can there be a f...
