Editing Fingerprint (section)

=== Pattern-based (or image-based) algorithms ===
Pattern based algorithms compare the basic fingerprint patterns (arch, whorl, and loop) between a previously stored template and a candidate fingerprint. This requires that the images can be aligned in the same orientation. To do this, the algorithm finds a central point in the fingerprint image and centers on that. In a pattern-based algorithm, the template contains the type, size, and orientation of patterns within the aligned fingerprint image. The candidate fingerprint image is graphically compared with the template to determine the degree to which they match.<ref name=ibia><!-- Minutia vs. Pattern Based Fingerprint Templates. (2003).
