This paper investigates the use of facial gestures for identity recognition. This is the first time that such a quantitative evaluation is conducted, comparing the analyses of 2D versus 3D dynamic data of verbal and nonverbal facial actions. Suitable data processing and feature extraction methods are examined, then a number of pattern matching techniques including the Fréchet distance, Correlat...

Facial expressions are one of the most important ways to communicate our emotional state. In popular culture and in the scientific literature on face processing, the eye area is often conceived as a very important - if not the most important - cue for the recognition of facial expressions.

Individuals with Autism Spectrum Disorders (ASD) report difficulties extracting meaningful information from dynamic and complex social cues, like facial expressions. The nature and mechanisms of these difficulties remain unclear. Here we tested whether that difficulty can be traced to the pattern of activity in "social brain" regions, when viewing dynamic facial expressions. In two studies, adu...

BACKGROUND This paper discusses the various methods and the materials for the fabrication of active artificial facial muscles. The primary use for these will be the reanimation of paralysed or atrophied muscles in sufferers of non-recoverable unilateral facial paralysis. METHOD The prosthetic solution described in this paper is based on sensing muscle motion of the contralateral healthy muscl...
