Prosopagnosia, [2] also known as face blindness, [3] is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact.
As of 2016, facial recognition was being used to identify people in photos taken by police in San Diego and Los Angeles (not on real-time video, and only against booking photos) [94] and use was planned in West Virginia and Dallas. [95] In recent years Maryland has used face recognition by comparing people's faces to their driver's license photos.
Bruce & Young Model of Face Recognition, 1986. One of the most widely accepted theories of face perception argues that understanding faces involves several stages: [7] from basic perceptual manipulations on the sensory information to derive details about the person (such as age, gender or attractiveness), to being able to recall meaningful details such as their name and any relevant past ...
People suffering from Capgras delusion are able to properly identify a face, but lack the covert recognition that is normally evoked by a familiar face. Before the delusion set in patients would normally have a sensation of familiarity and have a heightened response to faces that they recognize.
This is because processing inverted faces involves a piecemeal strategy. C.K.'s performance is compared to patients with prosopagnosia who are impaired in face processing but perform well identifying inverted faces. This was the first evidence for a double dissociation between face and object processing suggesting a face-specific processing system.
Many countries use a two-dimensional technology to identify people. The technology works by taking an image of a person's face and matching the image with databases. Usually the technology measures the distance between points of a person's face. Three-dimensional facial recognition using infrared also exists. [3]
Prosopometamorphopsia (PMO), [1] also known as demon face syndrome, [2] is a neurological disorder characterized by altered perceptions of faces. In the perception of a person with the disorder, facial features are distorted in a variety of ways including drooping, swelling, discoloration, and shifts of position.
