About

Biometric SDK is complete open-source Software Development Kit for face, iris and fingerprint modalities.

Workflow name Maven Central Maven Central Maven Central CocoaPods GitHub release

Structure

NOTE: Some modules are still under development.

  • io – defines functionality for working with images and biometric files.
  • iris – provides functionality for working with IRIS biometrics.
  • qualityControl – (unavailable) provides functionality for image quality calculation.
  • face – (unavailable) provides functionality for working with FACE biometrics.
  • finger – (unavailable) provides functionality for working with FINGERPRINT biometrics.

Initialize SDK

Call BiometricSdkFactory.configure(); for initial SDK configuration.
After that you can get SDK instance by calling getInstance() method.

IO

Image

Read/Write image from file

Image img = instance.io().readImage(path);
instance.io().write(img, "/opt/tmp", ImageFormat.PNG);

Read/Write image from bytes array

Image img = instance.io().readImage(bytes);
byte[] = instance.io().writeAsByteArrayImage(img, ImageFormat.PNG);

Iris

Extract

Operations for extracting iris texture from eye image.

Extract iris texture from image

Image eye = instance.io().readImage(path);
Img texture = instance.iris().extractor().extract(eye);

Encode

Operations for encoding iris texture to binary template.

Extract iris texture from image

byte[] template = instance.iris().encoder().encode(img);

Extracts and encodes iris texture from image

byte[] template2 = instance.iris().encoder().extractAndEncode(sample2);

Match

Operations for matching iris templates between each other.

Match templates

byte[] template1 = instance.iris().encoder().encode(template);
byte[] template2 = instance.iris().encoder().extractAndEncode(sample2);
boolean matches = instance.matcher().matches(template1, template2);

Communication

If you found a bug and can provide steps to reliably reproduce it, or if you have a feature request, please open an issue. Other questions may be addressed to the Biometric Technologies project maintainers.
