Abstract

The reconstruction of fingerprints from the output of sweep sensors is a crucial part of algorithms for fingerprint feature extraction. We present an efficient and accurate technique for fingerprint reconstruction from two-line sensors requiring sub-pixel methods. We propose a dedicated computation of the shift between two consecutive slices, yielding not only efficiency but also accuracy as we demonstrate by test data-sets.
