What exactly do you want to achieve? The fingerprint you are talking about most likely is saved in a Hash object containing the image converted to a fixed binary (01) representation.
This is a hello world example:
File img0 = new File("path/to/file.png");
File img1 = new File("path/to/secondFile.jpg");
HashingAlgorithm hasher = new PerceptiveHash(32);
Hash hash0 = hasher.hash(img0);
Hash hash1 = hasher.hash(img1);
double similarityScore = hash0.normalizedHammingDistance(hash1);
if(similarityScore < .2) {
//Considered a duplicate in this particular case
}
Be aware this step has to be repeated with multiple algorithms to reduce false positives. The different image matchers are utility classes to help performing such a task.
The example section points to a few classes explaining how to solve such a request. Please let me know if anything is unclear and we can work it out.
