Facial Recognition

	Facial Recognition Facial recognition or face recognition may refer to: * Face detection, often a step done before facial recognition * Face perception, the process by which the human brain understands and interprets the face * Pareidolia, which involves, in part, seeing images of faces in clouds and other scenes * Facial recognition system, an automated system with the ability to identify individuals by their facial characteristics {{disambig ...

picture info	Face Detection Face detection is a computer technology being used in a variety of applications that identifies human faces in digital images. Face detection also refers to the psychological process by which humans locate and attend to faces in a visual scene. Definition and related algorithms Face detection can be regarded as a specific case of object-class detection. In object-class detection, the task is to find the locations and sizes of all objects in an image that belong to a given class. Examples include upper torsos, pedestrians, and cars. Face detection simply answers two question, 1. are there any human faces in the collected images or video? 2. where is the located? Face-detection algorithms focus on the detection of frontal human faces. It is analogous to image detection in which the image of a person is matched bit by bit. Image matches with the image stores in database. Any facial feature changes in the database will invalidate the matching process. A reliable face-detection ...

picture info	Face Perception Facial perception is an individual's understanding and interpretation of the face. Here, perception implies the presence of consciousness and hence excludes automated facial recognition systems. Although facial recognition is found in other species, this article focuses on facial perception in humans. The perception of facial features is an important part of social cognition. Information gathered from the face helps people understand each other's identity, what they are thinking and feeling, anticipate their actions, recognize their emotions, build connections, and communicate through body language. Developing facial recognition is a necessary building block for complex societal constructs. Being able to perceive identity, mood, age, sex, and race lets people mold the way we interact with one another, and understand our immediate surroundings. Though facial perception is mainly considered to stem from visual intake, studies have shown that even people born blind can learn face ...

picture info	Pareidolia Pareidolia (; ) is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one sees an object, pattern, or meaning where there is none. Common examples are perceived images of animals, faces, or objects in cloud formations, seeing faces in inanimate objects, or lunar pareidolia like the Man in the Moon or the Moon rabbit. The concept of pareidolia may extend to include hidden messages in recorded music played in reverse or at higher- or lower-than-normal speeds, and hearing voices (mainly indistinct) or music in random noise, such as that produced by air conditioners or fans. Scientists have taught computers to use visual clues to "see" faces and other images. Etymology The word derives from the Greek words ''pará'' (, "beside, alongside, instead f) and the noun ''eídōlon'' (, "image, form, shape"). The German word was used in articles by Karl Ludwig Kahlbaum—for example in his 1866 paper "" ("On Delusion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
