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.
