Fingerprint Authentication", Computer Vision and Image Understanding, vol 113, pp. 979-992, 2009.

face recognition
Face Recognition

appearance changes

face recognition cont d
Face Recognition (cont’d)
  • Thermal IR spectrum
    • Not sensitive to illumination changes.
    • Low resolution, sensitive to air currents, face heat patterns, aging, and the presence of eyeglasses (i.e., glass is opaque to thermal IR).
  • Visible spectrum
    • High resolution, less sensitive to the presence of eyeglasses.
    • Sensitive to changes in illumination direction and facial expression.
