Java Challenge Response ExampleΒΆ
Initialize Challenge Response module
import org.sertiscorp.oneml.face.*;
ChallengeResponse challenge = new ChallengeResponse();
Initialize Challenge Response module from existing FaceDetector and FaceLandmarkDetector
import org.sertiscorp.oneml.face.*;
FaceDetector faceDetector = new FaceDetector();
FaceLandmarkDetector faceLandmark = new FaceLandmarkDetector();
ChallengeResponse challenge = new ChallengeResponse(faceDetector, faceLandmark);
Initialize Challenge Response module with licensing
import org.sertiscorp.oneml.face.*;
LicenseManager licenseManager = new LicenseManager();
licenseManager.setKey("LICENSE_KEY_VALUE_HERE");
licenseManager.activateKey();
ChallengeResponse challenge = new ChallengeResponse(licenseManager);
Initialize Challenge Response module with licensing from existing FaceDetector and FaceLandmarkDetector
import org.sertiscorp.oneml.face.*;
LicenseManager licenseManager = new LicenseManager();
licenseManager.setKey("LICENSE_KEY_VALUE_HERE");
licenseManager.activateKey();
FaceDetector faceDetector = new FaceDetector(licenseManager);
FaceLandmarkDetector faceLandmark = new FaceLandmarkDetector(licenseManager);
ChallengeResponse challenge = new ChallengeResponse(faceDetector, faceLandmark, licenseManager);
Run the module from videos
String vidPath = "path/to/video.mp4";
ChallengeResponseOps ops = new ChallengeResponseOps(true);
ChallengeResponseResult result = challenge.run(vidPath, ops);
Run the module from stream of images (can be used with opencv VideoCapture)
# if we can still read frame from image stream
ChallengeResponseOps ops = new ChallengeResponseOps(true);
while (can_read_frame):
# use any function to get each frame from image stream
Image frame = getOneFrame()
ChallengeResponseResult result = challenge.run(frame, ops)
challenge.reset()
Run the module with ImageBatch
// create ImageBatch
Utils utils = new Utils();
String vidPath = "path/to/video.mp4";
ImageBatch images = utils.videoToImages(vidPath);
ChallengeResponseOps ops = new ChallengeResponseOps(true);
// run ChallengeResponse with ImageBatch
ChallengeResponseResult result = challenge.run(images, ops);
Get result
System.out.println("status: " + result.getReturnStatus());
System.out.println("is_blink: " + result.isBlink());
System.out.println("number of blinks: " + result.getNumBlinks());
System.out.println("liveness_score: " + result.getLivenessScore());
Image bestFrame = result.getBestFrame();
Cleanup
faceDetector.delete();
faceLandmark.delete();
challenge.delete();
