This document is the final report of the Fingerprint Recognition Study of Children below the Age of 12 Years . The key findings of the study are:
• Growth has limited influence on fingerprint recognition
• Size (in terms of the dimensions of the relevant fingerprint characteristics) does not constitute any theoretical barrier for automated fingerprint recognition.
• Image quality (in terms of low contrast and distortion effects) is the ultimate problem for child fingerprints, and image quality is strongly influenced by size.
• Relevant quality metrics for fingerprints need revision with regard to the children case.
• Isotropic growth model may serve as a good approximation to cover changes over time.
• Alternative acquisition devices for fingerprints should be seriously considered in the future.
Apart from these major findings, the report provides a number of recommendations to improve the process of acquiring fingerprints from children.
