FACIAL EXPRESSION MEASUREMENT FOR ASSESSMENT, MONITORING, AND TREATMENT EVALUATION OF AFFECTIVE AND NEUROLOGICAL DISORDERS

摘要

Apparatus, methods, and articles of manufacture facilitate diagnosis of affective mental and neurological disorders. Extended facial expression responses to various stimuli are evoked or spontaneously collected, and automatically evaluated using machine learning techniques and automatic facial expression measurement (AFEM) techniques. The stimuli may include pictures, videos, tasks of various emotion-eliciting paradigms, such as a reward-punishment paradigm, an anger eliciting paradigm, a fear eliciting paradigm, and a structured interview paradigm. The extended facial expression responses, which may include facial expression responses as well head pose responses and gesture responses, are analyzed using machine learning techniques to diagnose the subject, to estimate the likelihood that the subject suffers from a specific disorder, and/or to evaluate treatment efficacy.
