Abstract
This paper proposes a new alignment method, which uses histograms based on minutiae orientations to correct rotational differences between two samples of the same fingerprint. Experimentation shows that the proposed alignment method is promising in terms of its accuracy, particularly for coarse rotational alignment. Evaluation of the method's speed proves that it is considerably faster than the exhaustive search alignment technique, which is typically used for aligning minutiae templates. The results obtained motivate the possibility of a hybrid alignment approach, where the proposed technique is used for fast and coarse rotational alignment of two minutiae templates, followed by a finer alignment provided by a different alignment strategy (such as the exhaustive search technique) for increased accuracy.
