The last method of fingerprint identification is called a complete match.
It involves selecting at least thirteen or more feature points on the target fingerprint and then matching them completely with the fingerprints in the database.
Only when all selected feature points are successfully matched does it signify successful fingerprint identification.
The system will give a special beep to indicate a successful match.
This method of fingerprint analysis is not commonly used by most people.
Unless the fingerprint matching is very straightforward, meaning the collected fingerprint is very clear, without any distortion, and can be compared visually with the imprinted fingerprint.
Another scenario is when someone highly skilled is very confident in their fingerprint preprocessing, with very clear feature point marking and calculation.
Which type is Lu Chuan?
The comparison of feature points is not a simple image processing task where it just needs to look similar.
