Functions

onAllCornersUsed

abstract fun onAllCornersUsed()

Called when all specified corners has been used, but accepted sample count has not been reached. Once this callback is called, the whole process is considered to be over.

onCriticalFacePresenceLost

abstract fun onCriticalFacePresenceLost()

Called when the process is unable to continue. Either the face is not detected anymore or the eyes are not visible clearly. Once this callback is called, the whole process is considered to be over.

onFinished

abstract fun onFinished(result: EyeGazeLivenessResult)

Called only once for the whole process. Once this callback is called, the whole process is considered to be over.

onProcessed

abstract fun onProcessed(detection: FaceAutoCaptureDetection)

Called when a camera image is processed.

provideConfiguration

abstract fun provideConfiguration(): EyeGazeLivenessFragment.Configuration

Provide Configuration for the Eye Gaze Liveness UI component.
