ELASTIC DEFORMATIONS IMPACT ON FINGERPRINT RECOGNITION PERFORMANCE
Elastic deformations are the strong negative factor in fingerprint recognition. The mechanical approach to fingerprint deformation modeling was employed to determine elastic deformation impact on fingerprint recognition. The statistic analysis of structure of elastic deformations was carried out. It revealed that an arbitrary deformation is the combination of elementary principal deformations: rotation, torsion, and traction. Finally, numerical measure for the impact of deformations on fingerprint recognition was found
