SourceAFIS is a fingerprint recognition engine that takes a pair of human fingerprint images and returns their similarity score. It can do 1:1 comparisons as well as efficient 1:N search. This is the Java implementation of the SourceAFIS algorithm.
byte[] probeImage = Files.readAllBytes(Paths.get("probe.jpeg"));
byte[] candidateImage = Files.readAllBytes(Paths.get("candidate.jpeg"));
FingerprintTemplate probe = new FingerprintTemplate(probeImage);
FingerprintTemplate candidate = new FingerprintTemplate(candidateImage);
FingerprintMatcher matcher = new FingerprintMatcher(probe);
double score = matcher.match(candidate);
boolean match = score >= 40;
