Cascade Classifier Circle Detection

I am completely new to the object detection. But I think my project can be realized very simple.

I setup a raspberry pi zero with a UV4L realtime video stream. UV4L already supports the face detection with a lbpcascade_frontalface.xml file.

For my use case I just want to detect a circle not a face. I want to highlight the circle in the picture and want to output the center coordinates.

I saw opencv has a function to detect circles. But how to creat a xml file which detect the circle?

Thank you in advance

i'd say: forget the idea of training some cascade on circles, as those don't have any "texture".

(think of what's inside a face, you don't have any detail in there)

(maybe this)
