Usage

• Either download this APK file

OR

• Clone this repository
• Open project in android studio
• Optional: Configure firebase if required. Check out comments in ReviewResults activity
• Compile, install the Apk
• Go to training, set an ID and capture a face to train. Repeat this a couple of times with different people and IDs
• Go to recognition, click scan and try to capture everyone in the video stream. The detected faces will be recognized and shown.
• Once done, stop scanning and click submit to review capture results. Implement the "Mark Attendence" button if required.

Known Issues & TODO

• Face recognition is not accurate. Far from it
• Recognition model gets created each time "Recognize" tab is clicked. Slows down as number of training images increase

Coding style issues

Hey, I was very impressed by this project and I wanted to contribute a little something considering the android/java coding style. It doesn't impact any usability feature, nor does it break something.
It's only cosmethics but it does improve readability when conferring to standards.
Thanks !
