Facial expression in schizophrenia
Biological Psychiatry, 1996Recent empirical studies have found that schizophrenics exhibit diminished observable facial expressivity in response to emotional stimuli (e.g., Berenbaum and Oltmanns 1992; Kring et al 1993; Kring and Neale 1996) yet report experiencing similar levels of emotion as their normal counterparts; however, it remains unclear whether schizophrenics are ...

2015 Annual IEEE India Conference (INDICON), 2015
Facial expression recognition, due to its wide research areas become active research topic. This paper presents comparative analysis of automatic Facial Expression Recognition by compensating effect of age on the recognition process by Weighted Least Square filtering. System uses Gabor filter and Log Gabor filter to extract facial features.

Geometry Guided Pose-Invariant Facial Expression Recognition
IEEE Transactions on Image Processing, 2020Driven by recent advances in human-centered computing, Facial Expression Recognition (FER) has attracted significant attention in many applications. However, most conventional approaches either perform face frontalization on a non-frontal facial image or

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 ...

Perceptual and Motor Skills, 2001
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.

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 ...

Pain Management, 2011
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 ...

Are Facial Expressions Reproducible?
The Cleft Palate Craniofacial Journal, 2003Objectives To determine the extent of reproducibility of five facial expressions. Design Thirty healthy Caucasian volunteers (15 males, 15 females) aged 21 to 30 years had 20 landmarks highlighted on the face with a fine eyeliner pencil. Subjects were asked to perform a sequence of five facial expressions that were captured by a three-dimensional ...

Facial Expression Recognition by De-expression Residue Learning
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018A facial expression is a combination of an expressive component and a neutral component of a person. In this paper, we propose to recognize facial expressions by extracting information of the expressive component through a de-expression learning ...
