Satellite photograph of a mesa in the Cydonia region of Mars, often called the "Face on Mars" and cited as evidence of extraterrestrial habitation. Pareidolia (/ ˌ p ær ɪ ˈ d oʊ l i ə, ˌ p ɛər-/; [1] also US: / ˌ p ɛər aɪ-/) [2] is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one detects an object, pattern, or ...
Pattern recognition is crucial not only to humans, but also to other animals. Even koalas, which possess less-developed thinking abilities, use pattern recognition to find and consume eucalyptus leaves. The human brain has developed more, but holds similarities to the brains of birds and lower mammals.
People often see hidden faces in things. Depending on the circumstances, this is referred to as pareidolia, the perception or recognition of a specific pattern or form in something essentially different. It is thus also a kind of optical illusion. When an artist notices that two different things have a similar appearance, and draws or paints a ...
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 ...
Pattern recognition is a cognitive process that involves retrieving information either from long-term, short-term, or working memory and matching it with information from stimuli. There are three different ways in which this may happen and go wrong, resulting in apophenia.
A modern definition of pattern recognition is: The field of pattern recognition is concerned with the automatic discovery of regularities in data through the use of computer algorithms and with the use of these regularities to take actions such as classifying the data into different categories. [4]
Scientifically, such imagery is generally characterized as a form of pareidolia.This is a false perception of imagery due to what is theorized as the human mind's over-sensitivity to perceiving patterns, particularly the pattern of a human face, in otherwise random phenomena.
Physiognomy as it is understood today is a subject of renewed scientific interest, especially as it relates to machine learning and facial recognition technology. [6] [7] [8] The main interest for scientists today are the risks, including privacy concerns, of physiognomy in the context of facial recognition algorithms.
