In the Automatic Fingerprint Identification System(AFIS)
we face the fact how to effectively use the huge curve information of fingerprint to describe fingerprint.This article proposes a novel algorithm;it embraces information of few fingerprint ridges nearby to extract a new characteristic which can describe the curvature feature of fingerprint.Experimental results show the algorithm is feasible
and the characteristics extracted by it can clearly show the inner macroscopic curve properties of fingerprint image and can be used for fingerprint verification as a supplement to the customary minutiae.The result also shows that this kind of characteristic is robust to noise and pollution.
