Android Question Smile detector to capture photo?

[personalapps]

Is there a library to detect smile or other gestures so it can be linked to some action like camera click ? OpenCV is too big and slow for such a task.

I found this ML Kit reference for face , contour ,smile and open eye detection: https://developers.google.com/ml-kit/vision/face-detection .Will this be implemented like other recent ML Kit features?
