Abstract

Image normalization examines the pixels of two frames, most commonly sequentially obtained sub-images, and mathematically determines the displacement of those pixels from the first frame to the second based on pixel data. The pixel data is obtained from a scanning device, and may be for example grayscale value. The image may be for example that of a user's fingerprint, and the image normalization used to form a computed image of the fingerprint from a plurality of sub-images obtained from a fingerprint scanner. The computed image may be stored, compared to a reference frame or otherwise processed, for example for identifying the user.
