How to get the current frame (as a Bitmap) for android facedetector in a Tracker event?


I have the standard com.google.android.gms.vision.Tracker example successfully running on my android device and now i need to postprocess the image to find the iris of the current face which has been notified in the event methods of the Tracker.
So, how do i get the Bitmap frame which matches exactly the com.google.android.gms.vision.face.Face i received in the Tracker events?
This also means that the final bitmap should match the webcam resolution and not the screen resolution.
One bad alternative solution is to call takePicture every few ms on my CameraSource and process this picture separately using the FaceDetector. Although this works i have the problem that the video stream freezes during takepicture and i get lots of GC_FOR_ALLOC messages cause of the single bmp facedetector memory waste.
