Compare 2 Fingerprints

Postby Toengel » Feb 23, 2010 09:27

Hi,

I have 2 acquisition images of the same finger and I want to compare them. However, I dont need a comparison score but I want to know which minutiae are found in both images. So, is it possible to get these minutiae?

Regards,

Alex

Hello,

yes it is possible to get pair of matched minutiaes. After a verification or identification, if the fingerprints are matched, matcher returns NMMatchDetails, which contains an array of pairs of matched minutiaes.

Hi,

thanks for your reply. I am using the Verifinger SDK Trial with Java...

I am using the following:

NMatcher matcher = new NMatcher();
int score = matcher.verify(template1, template2);

Additionally I found the following for the MatchDetails.

NFMatchDetails matchDetails = new NFMatchDetails();

However, I don't know how to link the matcher with the matchDetails. The verify()-method has only an int-value (the score) as result... In C# or C++ there are methods, where the verify() has an output for the details:
public int Verify(IntPtr template1, int template1Size, IntPtr template2, int template2Size, out NfmMatchDetails matchDetails);

How to solve this in Java?

Regards,

Hi,

unfortunatelly this functionality is not implemented in Java. But we provide a source code of Java wrapper so you can implement this functionallity by yourself.
