In verification of noisy fingerprints, best corresponding local structures could be inadequate candidates to estimate global alignments. Likewise, alignments using similarity histogram may produce biased or skewed solutions because of outliers caused by noises. We propose a global alignment algorithm which efficiently extracts major trend of transformation from the corresponding local structures. Since we use graph representation, the algorithm is executed very quickly and its complexity is O(n2), where n is the number of corresponding local structures. Experimental results show that the proposed algorithm performs well with noisy fingerprints and the average alignment error has been significantly improved compared with previous methods.
