Compatibility

• Minimum Android SDK : Viola Age 1.0.2 requires a minimum API level of 21.

Installation

Download the latest aar from jitpack or grab via

</dependency>

Usage

Kotlin

val violaAgeClassifier = ViolaAgeClassifier(listener)

violaAgeClassifier.findAgeAsync(bitmap) //asynchronous call using callback interface         

private val listener: AgeClassificationListener = object : AgeClassificationListener {

        override fun onAgeClassificationResult(result: List<AgeRecognition>) {}

        override fun onAgeClassificationError(error: String) {}
}


//OR using synchronous function call
val result:List<AgeRecognition> = violaAgeClassifier.findAgeSynchronized(faceBitmap)   //synchronous call   

with AgeOptions

val ageOption =
    AgeOptions.Builder()
               .enableFacePreValidation()
               .build()
violaAgeClassifier.findAgeAsync(bitmap,ageOption)

Java

ViolaAgeClassifier violaAgeClassifier = new ViolaAgeClassifier(listener);

violaAgeClassifier.findAgeAsync(bitmap); //asynchronous call using callback interface

private final AgeClassificationListener listener = new AgeClassificationListener() {
        @Override
        public void onAgeClassificationResult(@NotNull List<AgeRecognition> result) { }

        @Override
        public void onAgeClassificationError(@NotNull String error) { }
};

//OR using synchronous function call
List<AgeRecognition> result = violaAgeClassifier.findAgeSynchronized(faceBitmap);   //synchronous call

with AgeOptions

AgeOptions ageOption = new AgeOptions.Builder()
                .enableFacePreValidation()
                .build();
violaAgeClassifier.findAgeAsync(bitmap,ageOption)
