Recognizing Facial Expressions by Spatio-Temporal Analysis
نویسندگان
چکیده
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 developed. Recognizing six facial expressions, as well as eye blinking, are demonstrated on a collection of image sequences.

Automatically Recognizing Facial Expressions in the Spatio-Temporal Domain
We developed a computer vision system that automatically recognizes facial action units (AUs) or AU combinations using Hidden Markov Models (HMMs). AUs are defined as visually discriminable muscle movements. The facial expressions are recognized in digitized image sequences of arbitrary length. In this paper, we use two approaches to extract the expression information: (1) facial feature point ...

متن کاملAutomatic Recognition of Deceptive Facial Expressions of Emotion
Humans modify facial expressions in order to mislead observers regarding their true emotional states. Being able to recognize the authenticity of emotional displays is notoriously difficult for human observers. Evidence in experimental psychology shows that discriminative facial responses are short and subtle. This suggests that such behavior would be easier to distinguish when captured in high...
متن کاملFacial Expression Recognition Using a Dynamic Model and Motion Energy
Previous efforts at facial expression recognition have been based on the Facial Action Coding System (FACS), a representation developed in order to allow human psychologists to code expression from static facial “mugshots.” In this paper we develop new, more accurate representations for facial expression by building a video database of facial expressions and then probabilistically characterizin...
متن کاملRunning Head : SPATIO - TEMPORAL INFORMATION IN DYNAMIC FACES 2
A great deal of perceptual and social information is conveyed by facial motion. Here, we investigated observers’ sensitivity to the complex spatio-temporal information in facial expressions and what cues they use to judge the similarity of these movements. We motioncaptured four facial expressions and decomposed them into time courses of semantically meaningful local facial actions (e.g., eyebr...
