How to use custom dataset or model for face recognition?

[SeunghoHan]

Hi,

I want to recognize the user's face from a webcam in real-time by using OpenCV for unity lib. Actually, I'm a beginner at unity, so first I tried to use the face detection lib with the webcam and succeeded,

Then, I want to move on to the next phase, which recognizes the face in real-time and then trains the recognition model with my own or custom data. But, I didn't find an example of face recognition in real-time.

Are there any examples or codes related to face recognition in real-time that I haven't been able to find? Also, if there is, is there a way to use the recognition model which trained or fine-tuned on a custom dataset in Unity?
