A novel interactive biometric passport photograph alignment system

A novel framework for interactively acquiring images is developed in which uses real-time visual and audio cues to assist in guiding the user into correct alignment for compliance with European biometric passport regulations. Users pose in front of a camera using visual feedback from a monitor to approximately position themselves prior to an iris detection scheme used to calculate their roll (z- axis) alignment. Audio instructions are then provided to refine the posture. Blink detection is also used to ascertain the user's readiness to having their passport image taken.
