Facial Recognition(not detection)using tensorflow lite(on device) in Android

Using Tensorflow lite I am trying to find a way for facial recognition (not detection) using camera given picture.

I googled everything related to this but all are detecting face. I followed these links: 1. https://firebase.google.com/docs/ml-kit/android/detect-faces 2. https://medium.com/devnibbles/facial-recognition-with-android-1-4-5e043c264edc Any help will be appreciated. Thanks a lot in advance.
