Recognizing Facial Expressions by Spatio-Temporal Analysis
An approach for analysis and representation of facial dynamics for recognition of facial expressions from image sequences is proposed. The algorithms we develop utilize optical ow computation to identify the direction of rigid and non-rigid motions that are caused by human facial expressions. A mid-level symbolic representation that is motivated by linguistic and psychological considerations is...
متن کاملMeasuring facial expressions by computer image analysis.
Facial expressions provide an important behavioral measure for the study of emotion, cognitive processes, and social interaction. The Facial Action Coding System (Ekman & Friesen, 1978) is an objective method for quantifying facial movement in terms of component actions. We applied computer image analysis to the problem of automatically detecting facial actions in sequences of images. Three app...
متن کاملRecognizing Facial Expressions in Videos
Facial expression recognition plays a significant role in human-computer interaction systems, but remains an unsolved problem. In this paper, two competing approaches to detect seven basic facial expressions in videos are compared. One approach used Principle Component Analysis to project the training and testing faces onto the eigenspace, and categorized the testing faces using K nearest neigh...
متن کاملRecognizing Facial Expressions Automatically from Video
Facial expressions, resulting from movements of the facial muscles, are the face changes in response to a person’s internal emotional states, intentions, or social communications. There is a considerable history associated with the study on facial expressions. Darwin (1872) was the first to describe in details the specific facial expressions associated with emotions in animals and humans, who a...
متن کاملRecognizing emotion from facial expressions: psychological and neurological mechanisms.
Recognizing emotion from facial expressions draws on diverse psychological processes implemented in a large array of neural structures. Studies using evoked potentials, lesions, and functional imaging have begun to elucidate some of the mechanisms. Early perceptual processing of faces draws on cortices in occipital and temporal lobes that construct detailed representations from the configuratio...
