I have a face recognition and detection android app source code.
This code has already recognize and detect engine by dlib.
Also the source has cpp based NDK code of dlib engine.
I don't want you about face recognition accuracy.
I am fine about dlib accuracy.
Only need to implement following idea on exist app.
When detect a face on android camera, after recognize face, show person information and photo on list view.
it is okay to show a name of face.
I will provide code on chatting.
Please come to me if you already have dlib face recognition experience on android.
Please check uploaded sample video.
