A finger sensor may include a plurality of finger image sensing arrays for generating a respective plurality of finger image data sets based upon sliding finger movement over the finger image sensing arrays, and a processor cooperating with the finger image sensing arrays. The processor may determine finger movement based upon the finger image data sets, and generate a resampled finger image data set by resampling the finger image data sets based upon the determined finger movement. The processor may further deskew the finger image data sets when generating the resampled finger image data set.

Finger sensor apparatus using image resampling and associated methods

An apparatus and method for enrolling at least one fingerprint and determining a match of a new fingerprint thereto uses data related to fingerprint ridge flow for matching a desired area segment of a new fingerprint to a corresponding area segment stored in a database. The apparatus generates and stores enrollment data based upon fingerprint ridge flow over a plurality of area segments for the at least one fingerprint, senses a new fingerprint, and generates sensed data based upon fingerprint ridge flow of the new fingerprint over at least one desired area segment of the plurality of area segments. The method also preferably includes comparing the enrollment data and sensed data to determine whether the new fingerprint matches an enrolled fingerprint. The generating of sensed data preferably comprises identifying and generating sensed data for only a single desired area segment in one embodiment. In another embodiment, a plurality of area segments are identified and processed to achieve a desired performance.
