SourceAFIS Perfomance - NetBeans

[Dunsin O]

I am using NetBeans IDE for development. After I cloned the project from bitcucket and imported the project I noticed it had to download some dependencies at first build.

At the moment the matching algorithm works fine but I'm concerned about the total time it takes to execute - I observe an average run time of 6-7 secs for 1:1 matching.

Below is my code:

import java.io.IOException;

public class FingerPrintRun {

    public static void main(String [] parms)
    {
        try
        {
            System.out.println("Starting Test..");

            byte[] probeImage = Files.readAllBytes(Paths.get("/Users/dunsin/desktop/test4.png"));
            byte[] candidateImage = Files.readAllBytes(Paths.get("/Users/dunsin/desktop/test3.png"));

            FingerprintTemplate probe = new FingerprintTemplate()
                .dpi(500)
                .create(probeImage);

            FingerprintTemplate candidate = new FingerprintTemplate()
                .dpi(500)
                .create(candidateImage);

            double score = new FingerprintMatcher()
        .index(probe)
        .match(candidate);

            double threshold = 40;
            boolean matches = score >= threshold;

            System.out.println("Result of Fingerprint verification - Similarity score is "+score+" and match is "+matches);
       }
       catch(IOException exception)
       {
           System.out.println("Exception is "+exception);
       }

    }

}

This benchmark has numerous issues:

• build time overhead
• JVM launch overhead
• JVM is not warmed up
• 2x image I/O and 2x feature extraction is included in benchmark of matching speed
• index() method is included in timing of match() method
• match() method is tested on matching fingerprint pair (rare in 1:N)
• low data diversity - only one fingerprint pair
