Which of the following methods is more microscopic and will analyze the direction of the ridges of
the fingerprints for matching?

A.
None of the choices.

B.
Flow direct

C.
Ridge matching

D.
Minutia matching

Explanation:
There are two approaches for capturing the fingerprint image for matching: minutia matching and
global pattern matching. Minutia matching is a more microscopic approach that analyzes the
features of the fingerprint, such as the location and direction of the ridges, for matching. The only
problem with this approach is that it is difficult to extract the minutiae points accurately if the
fingerprint is in some way distorted.
The more macroscopic approach is global pattern matching where the flow of the ridges is compared
at all locations between a pair of fingerprint images; however, this can be affected by the direction
that the image is rotated.
