Application for android face recognition, where to start?

Question

Pattern recognition

Guys, hello everyone!
I have an idea that I don't know how to implement yet.
The bottom line is this: I need to develop an application for android that will allow you to recognize faces in real time (similar to Snapchat, where you can try on various wigs, glasses, etc. while filming yourself on the front camera of your smartphone).
Tell me where to start and how to approach the implementation of such an idea? What difficulties may arise?
Thanks for any advice.

Answer 1

And do you know how to program? Especially for Android? What is "pattern recognition"? If not, then the first tip is to start with this.
"What difficulties may arise " - the main difficulty is the incompetence of the project participant. To check whether your competence is sufficient, try to answer the question - why use face recognition when trying on a wig or glasses ?
