摘要

A method and system for synthesizing multiple fingerprint images into a single synthesized fingerprint template. Sets of features are extracted from each of three or more fingerprint images. Pair-wise comparisons identifying correspondences between sets of features are performed between each set of features and every other set of features. Transformations (translation and rotation) for each set of features are simultaneously calculated based on the pair-wise correspondences, and each set of features is transformed accordingly. A synthesized fingerprint template is generated by simultaneously registering the transformed sets of features.
