  2. Active appearance model - Wikipedia

    en.wikipedia.org/wiki/Active_appearance_model

    An active appearance model (AAM) is a computer vision algorithm for matching a statistical model of object shape and appearance to a new image. They are built during a training phase. A set of images, together with coordinates of landmarks that appear in all of the images, is provided to the training supervisor.

  3. Eigenface - Wikipedia

    en.wikipedia.org/wiki/Eigenface

    Eigenface provides an easy and cheap way to realize face recognition in that: Its training process is completely automatic and easy to code. Eigenface adequately reduces statistical complexity in face image representation. Once eigenfaces of a database are calculated, face recognition can be achieved in real time.

  4. Iris recognition - Wikipedia

    en.wikipedia.org/wiki/Iris_recognition

    Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual's eyes.. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some ...

  5. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    In a similar way, certain particular patches and regions of the cortex are more involved in face recognition than other object recognition. Some studies tend to show that rather than the uniform global image, some particular features and regions of interest of the objects are key elements when the brain needs to recognise an object in an image.

  6. Face perception - Wikipedia

    en.wikipedia.org/wiki/Face_perception

    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 ...

  7. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    The visual system performs a number of complex tasks based on the image forming functionality of the eye, including the formation of monocular images, the neural mechanisms underlying stereopsis and assessment of distances to (depth perception) and between objects, motion perception, pattern recognition, accurate motor coordination under visual ...

  8. Three-dimensional face recognition - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional_face...

    3D model of a human face. Three-dimensional face recognition (3D face recognition) is a modality of facial recognition methods in which the three-dimensional geometry of the human face is used. It has been shown that 3D face recognition methods can achieve significantly higher accuracy than their 2D counterparts, rivaling fingerprint recognition.

  9. Face space - Wikipedia

    en.wikipedia.org/wiki/Face_space

    Face space is useful for accounting various aspects of face recognition including, the own-race bias, [4] distinctiveness and caricature effects. [5] The framework has also provided useful applications in the design of forensic techniques for eyewitness identification, such as facial composites and police lineups .
