METHOD OF TRANSFORMING MINUTIAE USING TAYLOR SERIES FOR INTEROPERABLE FINGERPRINT RECOGNITION BETWEEN DISPARATE FINGERPRINT SENSORS
Abstract:
A method of transforming minutiae using the Taylor series for interoperable fingerprint recognition between disparate fingerprint sensors, which parses the fields of a Standard Interchange Format (SIF) template having the level of minutiae proposed in SC37, extract information fields corresponding to resolution, image size, and minutiae, corrects the locations of minutiae constituting the template, and standardizes the minutiae, thus increasing a recognition rate for fingerprint matching, and which applies transformation parameters using the Taylor series to a golden template that is generated using a plurality of samples for the same fingerprint which are input from a plurality of disparate fingerprint recognition sensors, thus improving recognition performance and reliability of matching between the disparate sensors that use the transformation of minutiae merely by correcting the locations of the minutiae, without correcting resolution or distortion characteristics. In the minutiae transformation method, a golden template, which is a template including visible minutiae, is created. Transformation parameters are calculated using the Taylor series. A location of minutiae data calculated from the SIF templates is corrected using the transformation parameters.
