Modelling Plastic Distortion in Fingerprint Images

摘要

This paper introduces a plastic distortion model to cope with the non-linear deformations characterizing fingerprint images taken with on-line acquisition sensors. The problem has a great impact on several practical applications, ranging from the design of robust fingerprint matching algorithms to the generation of synthetic fingerprint images. The experimentation on real data validates the model and demonstrates its efficacy in registering minutiae data from highly distorted fingerprint samples.
