Griffin investigators facial recognitin software

The ability to recognize faces and words is crucial for social communication. A close relationship between the face recognition and the word recognition has been documented in numerous studies involving EEG, evoked potentials, functional MRI, as well as clinical data in patients with impaired face perception who suffered from some word recognition inability. Therefore, identifying common mechanisms underlying the recognition of verbal and non-verbal stimuli is relevant not only for normal physiology and cognitive neuroscience, but also for the clinical conditions of agnosia of various etiologies. We hypothesized that EEG patterns related to the recognition of words and faces might be influenced by both the stimulus-type factor word or face and the factor of familiarity.

A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database. It is typically used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. These features are then used to search for other images with matching features. A probe image is then compared with the face data.

Effective date : A computer automated 3D sketch artist process for generating a computer 3D image of an individual includes the steps of generating a morphable head model as a starting point to develop a composite 3D like picture of the individual by analysis of a prerecorded data base of 3D face pictures, selecting a lighting model to best depict the individual, selecting a mouth model from a prerecorded data base of mouth shapes to best depict the individual's mouth and teeth, selecting an expression model for the individual's composite 3D sketch from a prerecorded data base of facial expressions, and manipulating the generated composite 3D sketch with various morphing tools to selectively modify the composite sketch to best conform to the individual's characteristics. Application No. Law enforcement professionals have used professional sketch artists for years to generate a composite of a suspect's face from a witness's description. However, many police departments are unable to staff the high-level of skill necessary to make this important police function effective.
