Detector for finding FirebaseVisionFaces in a supplied image.

A face detector is created via getVisionFaceDetector(FirebaseVisionFaceDetectorOptions) or getVisionFaceDetector(), if you wish to use the default options. For example, the code below creates a face detector with default options.

 FirebaseVisionFaceDetector faceDetector =
    FirebaseVision.getInstance().getVisionFaceDetector();
 
To perform face detection in an image, you first need to create an instance of FirebaseVisionImage from a Bitmap, ByteBuffer, etc. See FirebaseVisionImage documentation for more details. For example, the code below creates a FirebaseVisionImage from a Bitmap.
      FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(bitmap);
Then the code below can detect faces in the supplied FirebaseVisionImage.

 Task<List<FirebaseVisionFace>> task = faceDetector.detectInImage(image);
 task.addOnSuccessListener(...).addOnFailureListener(...);
