Android/Java Face Recognition: gender, age, emotions

Question

Is there any simple library/framework for Android/Java which can detect a face on a picture and give me some information about the person on the picture? I mean information like gender, age, emotions (smiling, sadness, anger) ...

I have tried Face++ and Microsoft's Project Oxford. It works great but I would want to use something like that without the Internet connection.

The features in Google Play Services look great but it gives me only the smiling probability, not the age, gender etc.

Answer 1

I have created an Android library for face detection and cropping. The library is compatible with both java and kotlin language.

It has the following features:

• Prominent face detection
• Multiple face detection
• Automatic face crop
• Face classification information
• Age classification support

Referee the Viola SDK for the implementation details.

Example

val viola = Viola(listener)
viola.addAgeClassificationPlugin(context) //optional, available via external dependency

viola.detectFace(bitmap)

private val listener: FaceDetectionListener = object : FaceDetectionListener {

        override fun onFaceDetected(result: Result) {}

        override fun onFaceDetectionFailed(error: FaceDetectionError, message: String) {}
}
