Abstract
A method for reconstructing a fingerprint image from a plurality of frames captured from swipe fingerprint sensor is disclosed. The method is based on a motion estimation between consecutive fingerprint frames. Only a portion of each frame is used to obtain the motion estimate to minimize system resources necessary for reconstructing the fingerprint image.
