摘要：
Different with a traditional orientation analysis or frequency analysis which is commonly used for the fingerprint reference point determination, a new fingerprint reference point determination method based on a novel inconsistency feature obtained from the relationship between ridgelines and curves of a fingerprint is proposed. For the proposed method, an improved enhancement method is introduced and the posterior probability theory is used to determine the reference point in pixel precision. Experimental results demonstrate its feasibility, validity and ability independent of the quality and types of fingerprints.
