Hi,
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
